VCCR300 Series Overview

The VCCR300 series of conduction cooled power supplies have been designed to 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 input voltage has a wide range of 33.6V to 160V which covers
the full requirements for the standard 48V, 72V, 96V and 110V railway battery voltages outlined in EN50155 and suitable for a variety of Battery
Electric Vehicle (BEV) and other demanding industrial applications. The high efficiency design minimises heating resulting in a wide operating
temperature range of -40°C to +70°C (+85°C 10 mins) with minimal cooling requirement. Output voltages of 12V, 24V, 36V and 48V are available
with a wide adjustment range of 90% to 125%. Protections including 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 paralleled while sharing the
load equally. 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 adjusted to meet 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 3
EMC emissions and immunity exceed the requirements of EN50121-3-2, EN55035 and EN55032 class B. As with all Vox products, our world class
sales, applications and engineering teams are available to support design-in of the VCCR300 series.
