Description:
The VCCR300 conduction cooled power series provide a rugged and highly reliable DC/DC power source that can deliver a silent 300 Watts of power in a 7.43 x 4.6 x 1-inch low profile package. The wide DC input voltage range covers the full requirements for standard 48V, 72V, 96V and 110V railway battery requirements detailed in EN50155 and suitable for a variety of Battery Electric Vehicle (BEV) and other demanding industrial applications. The high efficiency design minimises heating which results in a wide operating temperature range of -40°C to +70°C (+85°C 10 mins) with minimal cooling requirement. Standard output voltages available are 12V, 24V, 36V and 48V all of which have a wide adjustment range of 90% to 125%. Protections include over-voltage, over-current and over temperature are provided while DC_OK and warning signals indicate the status of the PSU. An adjustable droop mode current share allows multiple units to be parallel connected to achieve higher power levels whilst sharing the load equally between each VCCR300 product. Internal fusing and 10ms full power holdup are included as standard. A remote shutdown signal can place the unit in a low power standby mode and the input undervoltage level can be programmed to meet specific application requirements. The series meets the requirements of the latest railway standards (EN50155), MIL-STD-810G (Shock & Vibration) and is approved to the latest industrial safety standards (IEC/UL62368-1 3RD Edition). EMC emissions and immunity exceed the requirements of EN50121-3-2, EN55035 and EN55032 class B. |
