500W 3U DC Power Converters with AC or DC Inputs

Schaefer, Inc. announces the C/B 600 Series of dc-dc and ac-dc converter modules and battery charger (B600 models). The highly-reliable, compact and rugged 3U design uses industrial-grade components and provides a high-density, space saving solution for applications in industries such utility, oil/gas, automation, heavy industrial, military, telecom/datacom, alternative energy, transit/railway, process control, and power stations.

The C/B 600 Series delivers up to 500W of power and offers dc input voltage range of 10- to 380-Vdc with seven input range choices. AC input options are single-phase 115Vac or 230Vac (with or without PFC) or three-phase inputs of 3x200Vac. These modules are single output and are available in 12 standard ranges from 5- to 400-Vdc. All outputs are adjustable and tightly regulated to 0.2% (load) and 0.1% (line). Featuring natural convection cooling and a standard operating temperature range of –20 to +75 degrees C (derate 2.5%/degree C from +55 degrees C), with an option for -40 to +75 degrees C operation.

Modules are housed in an industry-standard 3U form factor for insertion into 19” sub-racks or optional wall, chassis and DIN-Rail mounting are available. All models have comprehensive protection circuitry including over-voltage protection, current limit protection on the output, and thermal shutdown with auto restart. Options include parallel/redundant operation, inhibit, Power-OK/DC-OK alarms, system reset signaling, active current sharing and programming/monitoring functions, etc.
