Description

30-Second Fit Check

HV system match: 750VDC rated; 740–800VDC full load; 700–740VDC derating to 60%.
Forward rating: 13,500W to 14.5VDC (932A) with 1% voltage accuracy.
Reverse rating: 10,800W rated input capacity; HV output 700–770VDC full load (770–800VDC derating to 70%).
Integration: CAN communications + status indicator lamps.
Mechanical: 300×220×86mm; <5.5kg; forced-air cooling path must be supported.
Constraint: LV output >25VDC can cause power failure—validate control strategy and load transients.

What It Is + Why It Matters

Bidirectional power flow: Helps support “energy recyclable” test/aging setups where power direction changes.
Efficiency evidence: 94.5% peak efficiency at 750VDC is stated (your realized efficiency depends on operating point).
High-frequency isolation mode: Listed for the module’s isolation approach.
EMC statement: Datasheet states meeting EN55032; treat as a component-level claim and verify at system level.

Key Specs (Evidence)

Forward: 13,500W; HV input ≤20A
HV input: 750VDC rated; 740–800VDC full load; 700–740VDC derating to 60%
LV output: 14.5VDC; 932A; 1% accuracy; 500mV ripple
Reverse: Rated input capacity 10,800W; LV input 14.5VDC; 745A
Reverse HV output: 700–770VDC full load; 770–800VDC derating to 70%

Integration & Controls

Communication: CAN
Indicator lamps: Operation Blue; Fault Red
Cooling: Forced air cooling, intelligent control
Airflow: Rear inlet & front outlet (front: fan; rear terminal)
Operating environment: -10°C to 45°C full load; 45–60°C derating use; altitude derating listed above 1000m

Best For / Not For

Best for: Cell formation and test equipment; energy recyclable power aging equipment.
Not for: Designs outside the published HV/LV ranges; applications requiring protocols other than CAN; enclosures that restrict forced airflow; projects needing guaranteed third-party certifications without model confirmation.

Typical Applications

Cell formation and test equipment
Energy recyclable power aging equipment
Bidirectional testing and energy storage scenarios (as positioned)

Selection Checklist

Provide HV nominal/min/max so we can confirm full-load vs derating.
Confirm LV output target is 14.5VDC; plan for <25VDC LV constraint.
State whether you need 10.8kW reverse continuously or intermittently.
Confirm airflow orientation and clearance for the fan face.
Confirm CAN is acceptable for your controller/network architecture.

Compliance & Protections

EMC: Datasheet states meeting EN55032.
Standards wording: Datasheet states comply with UL/CE/CCC—certifications may vary by model; see datasheet.
Protection: Fault protection is stated; over-temperature shutdown after overload is noted.

RFQ Quick Checklist

Quantity • Delivery target • HV bus (nom/min/max) • Forward kW • Reverse kW • LV 14.5V setpoint • CAN needed (Y/N) • Airflow/clearance • Ambient & altitude

Note

Final compliance/performance depends on end-product integration and verification testing (wiring, grounding, enclosure, EMC plan, and thermal conditions).
