Power conversion & system integration
Make power part of your system's control, test and maintenance workflow.
On models with the required digital features, operating data, approved settings and fault information can help you bring up equipment, repeat configurations and diagnose problems. Start with your input, load and cooling requirements, then confirm the selected module's interface and functions.
Selection and supply inquiries. Availability, lead time and supporting documentation are confirmed for the selected model.
Specifications below are selection summaries. Product files are not hosted for download, and this website does not accept file uploads. For the current datasheet/spec, drawings or detailed operating conditions, email market@jingmusecurity.com.
View documented digital functions and typical performance plots →Turn supported monitoring and configuration into a repeatable engineering workflow. Confirm each function, host interface and command set for the selected module before design-in.
Verify available telemetry, accuracy, update rate and measurement conditions in the selected model's documentation.
Confirm allowed adjustment ranges, start-up defaults, write protection and whether settings persist after power cycling.
Confirm fault flags or history, retention, interface levels, commands and host compatibility. PMBus / I²C and remote access are model-specific, not assumed.
Digital management does not by itself establish higher efficiency, lower ripple, faster transient response or lower cost. Compare the selected models under the same input, load and thermal conditions, and review isolation, protection and derating requirements separately.
1/16, 1/8 and 1/4 brick formats cover different nominal output ratings from 80 W to 420 W across the catalog. The 28 V and 48 V labels describe nominal input buses, not the actual operating range. Use the row for the selected series below.

From documented functions to model-level curves
Extracted from supplied 2025V2 specification documents, reviewed on 2026-10-29. These are typical characteristics from those documents, not independent Jingmu measurements or guaranteed limits. Original plots without company identifiers are reproduced without redrawing data, axes or legends; documented conditions appear alongside each plot.
| Digital function | Documented capability for this series | Integration value and confirmation |
|---|---|---|
| Operating telemetry | Input voltage, output voltage, output current and temperature readings. | Relate operating status to equipment load and test records; confirm accuracy and update rate. |
| Runtime parameter settings | Output voltage, overcurrent threshold, overtemperature threshold and soft-start rise time. | Define approved settings for a power rail; confirm allowed ranges and protection behavior. |
| PMBus digital interface | Clock/data interface for parameter reading and writing; the documentation describes digital PID/PWM control separately. | Plan host communication and readback checks; obtain the actual command set and electrical levels. |
| Ready and fault signals | PGOOD output-ready indication and a fault-alert signal, in addition to the digital interface. | Coordinate equipment startup and fault handling; check signal levels, timing and recovery. |
| Input-side / output-side enable | Separate RC and EN controls; output-side control requires input-side enable to be on. | Choose the correct positive/negative-logic order code and check the model-specific pinout. |
| Saved configuration | The supplied application section states that configured parameters are retained. | Plan power-cycle/readback acceptance checks; confirm firmware, defaults and programming-tool scope. |
This function table is a documented 2828x-240x example, not a claim for all 66 series. Software, USB programmers and remote-management platforms are not listed as standard inclusions; confirm the actual scope by email.

Our power catalog is digital only. Analog approaches below are engineering comparisons, not an additional product line. Confirm digital management functions for each model.
| Decision | With digital management (model-specific) | Analog approach and comparison boundary |
|---|---|---|
| Visibility | Bring supported telemetry and fault information into the host to aid troubleshooting. | External sensing and management can add similar functions; compare accuracy, update rate and integration effort. |
| Configuration | Set supported output, startup or protection parameters within documented limits and read them back. | Hardware settings or external control are alternatives; compare ranges, defaults, persistence and write protection. |
| System coordination | Use the actual protocol, command set and alarm behavior for host supervision. | A digital interface does not establish a digital control loop. Validate faults and recovery in either architecture. |
| Electrical performance and cost | Evaluate the selected model under comparable conditions, not the digital label. | Match input, load, temperature, cooling and measurement bandwidth before comparing efficiency, ripple, transients and total cost. |
Start with the equipment task, then connect power selection to control, test and maintenance. These are requirement scenarios, not delivered case studies; confirm each function for the selected model rather than all 66 series.
Customer task: Bring up multiple power rails and assess burst-load behavior in the complete equipment.
Digital-management value: Supported sequencing, enable and fault information can help the host coordinate startup and relate abnormal events.
Acceptance focus: Confirm actual signals and commands. Validate load steps under matched input, load and thermal conditions; digital features do not establish performance.
Connect power selection to RF requirementsCustomer task: Link power configuration and operating state to test records when reviewing differences.
Digital-management value: Supported configuration readback and telemetry can add context to repeatability checks and troubleshooting.
Acceptance focus: Confirm time correlation, readings and interfaces. A digital module is not a programmable laboratory supply; automated test software is a separate scope to confirm.
Review test-platform requirementsCustomer task: Investigate intermittent power problems before planning an on-site maintenance visit.
Digital-management value: Supported status, telemetry and fault context can inform remote diagnosis.
Acceptance focus: Confirm log retention, who records it and communication-loss behavior. Monitoring alone does not establish predictive maintenance or remaining life.
Check monitoring and host-integration needsCompare these four areas against the same functions and acceptance conditions. Any time or cost saving requires project validation.
Compare which sensing, supervision and control components are still required; do not assume full integration.
Include bus wiring, connectors, interface isolation and board space.
Include drivers, configuration control, communication-loss tests and revision maintenance.
Compare diagnosis, configuration restoration, site service and training effort.
The selection tables cover 66 series references in six groups: 1/16, 1/8 and 1/4 brick modules for nominal 28 V or 48 V input buses. Listed nominal power ratings span 80–420 W across different models. Each row defines its own input range, output voltage and power; these are not interchangeable combinations or stock confirmations.
The practical benefits are better visibility during bring-up, repeatable approved settings and more context for fault diagnosis. Models with the relevant functions can expose operating data and allow documented configuration through host control. Confirm readable values, commands, limits, persistence, tools and host integration for the selected model; these functions are not guaranteed across every series.
Evaluate it when equipment needs monitored rails, repeatable configuration, coordinated startup or fault information. Compare a suitably equipped digital module with the complete analog-plus-supervisor solution, including sensing, connections, host software, validation and service. Confirm electrical, mechanical, thermal and interface compatibility; a matching brick size is not proof of a drop-in replacement.
No. Digital control describes the regulation loop. Digital management covers functions such as configuration and telemetry, which can also be added to an analog control loop. An interface alone proves neither the loop architecture nor a full command set. Confirm architecture, protocol and supported functions separately for the exact order code.
No. Confirm the selected model's communication interface, command set, enable logic, power-good and fault signals, start-up defaults and protection limits. A digital label does not establish higher efficiency, lower ripple or faster transient response; compare measured specifications under the same input, load and thermal conditions.
No. The x characters are placeholders, not a complete order code. Confirm the exact ordering suffix, input operating range, output rail, enable logic, mechanical drawing, pinout and cooling/derating conditions before ordering. A catalog power rating is not a guarantee of continuous full-power operation at every temperature or input voltage.
