Specifications
INPUT
Voltage: 180 – 450VDC. Power delivered in the operational
range will depend on Operating Envelope
Transient Voltage: Up to 470VDC, down to 150V
Inrush Current: 25A Maximum under cold start conditions
Efficiency: Up to 94%

Parallel Use: May be paralleled with other like units or
a battery for increased system output
Temperature Coefficient: <+/- 0.02% per oC
Dimensions: H59 x W165 x D390 mm
(2.3 x 6.5 x 15.35 inches) See outline drawing
Weight: 5.6kg (12.3lb)
PROTECTION
Output Over-Voltage: Output Hiccup on OV
Output Over-Current: The converter becomes a
current source during OC, down to short circuit
Over-Temperature: Shutdown with auto recovery
COMMUNICATION
Communication Protocol: J1939 CAN Bus
CAN Bus Status Message: Output Current, Output
Voltage set and monitor, Input Power (calculated),
Heat Sink Temperature and fault signals.

Input Over-current Protection: Internal 20A Fuse
OUTPUT
Voltage: 13.5VDC Nominal / 10 – 15VDC Adjustment
Range via CAN command
Current: 200A DC Maximum
Power: 2700W Maximum
Ripple and Noise: 400mVp-p (20MHz Bandwidth)
Load Regulation: 2.5% Droop from No Load to Full Load
(Designed to support droop current share when paralleled
with other similar units) Lower droop options available

Electronic Control Inputs
Remote Enable: Application of >7.8V input signal will
enable the units Output. Less than 7.8V, or open circuit
on this pin disables output.
Connectors:
Input: IP67/IP6k9k connector rated to 600VDC
Output: Heavy Duty Studs / Positive = ½-13;
Negative = M10x1.5 Threaded Studs
Control: IP67/IP6k9k connector (Molex MX150L
series)
