Description

30-Second Fit Check

HV bus: Rated 750VDC; full-load range 740–800VDC (700–740VDC derating to 60%).
Forward power: 13,500W to a 14.5VDC output (932A).
Reverse power (energy return): Rated input capacity 10,800W; HV output 700–770VDC full load (770–800VDC derating to 70%).
Controls/Comms: CAN communication (confirm your controller integration needs).
Thermals: Forced-air cooling; verify airflow path and enclosure clearance.
Hard constraint: LV side exceeding 25VDC can cause power failure—confirm your setpoints and transients.

What It Is + Why It Matters

Bidirectional DC-DC BPM: Designed for energy flow in both directions to support formation/test and energy-recyclable aging workflows.
High-frequency isolation: Helps with system-level partitioning when integrating HV and LV sections.
Peak efficiency evidence: Datasheet lists 94.5% peak efficiency at 750VDC (interpret in the context of your operating point).
EMC note: Datasheet states “meeting EN55032” (final compliance depends on your end-product design and verification testing).

Best For / Not For

Best for: Cell formation and test equipment; energy recyclable power aging equipment.
Not for: HV buses outside the specified ranges; systems requiring a non-CAN interface; applications where LV excursions may exceed 25VDC; designs that cannot support forced-air airflow.

Typical Applications

Cell formation and test equipment
Energy recyclable power aging equipment
Bidirectional testing workflows (per datasheet positioning)
Energy storage-related scenarios (per datasheet positioning)

Selection Checklist

Confirm your HV bus stays in the full-load window (or accept derating behavior).
Confirm your LV target is 14.5VDC and that LV transients will not exceed 25VDC.
Check forward vs reverse power needs (13.5kW forward / 10.8kW reverse).
Plan airflow (rear-in/front-out) and provide clearance for the fan face.
Validate ambient + altitude derating against your site conditions.
Confirm CAN integration (IDs, update rate, harness routing—system-level details are on you).

Compliance & Protections

EMC claim: Datasheet states “meeting EN55032.”
Standards note: Datasheet states “comply with UL, CE, CCC and other standards”—certifications may vary by model; see datasheet.
Protection note: Datasheet mentions “perfect fault protection function” and shutdown due to over-temperature after overload.
