Description

30-Second Fit Check

HV class: 750VDC rated; 740–800VDC full-load window (700–740VDC derating to 60%).
Forward conversion: 13,500W into 14.5VDC output (932A).
Reverse capability: 10,800W rated input capacity; HV output 700–770VDC full load (770–800VDC derating to 70%).
System interface: CAN communications; status LEDs (Blue run / Red fault).
Cooling + packaging: Forced-air cooling; 300×220×86mm; <5.5kg.
Don’t skip: LV output exceeding 25VDC can cause power failure (design for transients).

What It Is + Why It Matters

Bidirectional BPM: Supports energy flow in both directions for bidirectional testing/formation workflows.
Soft-switching positioning: Datasheet highlights soft switching and high efficiency in both directions.
Peak efficiency evidence: 94.5% peak efficiency at 750VDC is listed as a reference point.
Integration clarity: CAN + defined airflow direction help de-risk mechanical/electrical fit checks.

Selection Checklist

Confirm HV bus min/max vs 740–800VDC full load and derating behavior below 740VDC.
Check LV behavior: 14.5VDC target; ensure transients won’t exceed 25VDC.
Size mechanical: 300×220×86mm; ensure airflow direction is supported.
Match power flow needs: 13.5kW forward vs 10.8kW reverse.
Confirm CAN fits your controls roadmap.

Compliance & Protections

EMC claim: Datasheet states meeting EN55032 (EN 55032 is an emissions standard used in EMC assessments).
Standards wording: Datasheet states comply with UL/CE/CCC—certifications may vary by model; see datasheet.
Protection note: Fault protection is stated; shutdown due to over-temperature after overload is noted.
