Wide input voltage range (32-96VDC) Water & dust proof (IP67), robust and reliable Operating temperature range: -40°C to +90°C Protections: Input Reverse Polarity Protection, Input UVLO, Output OCP, SCP, OVP, OTP • Parallel operation capability • Control ON/OFF function Features Regulated Converter Description The RMOD500-W DC-DC converter is ideally for the use in all off-highway electric vehicles. This family is an extremely robust plug & play module with 500 Watts, which generates the isolated Vout = 12.4 / 13.7 / 24.5VDC low voltage network from the traction battery level. The wide input voltage range 32-96V covers the common 48V and 80V battery voltages in this off-highway segment. Thanks to the waterproof and dust proof housing construction, the devices can directly be connected mechanically and thermally to the chassis (i.e. at any point on the vehicle) and operate reliably even under the most adverse conditions.

Use the same wire length for each power supply (star connection) and energize all units at the same time to avoid triggering overload protection. For operation with more than two power supplies in parallel operation, please contact RECOM technical support for advice. 1 +Vin +Vout +Vin +Vout PACKAGING INFORMATION Parameter Packaging Dimension...
