The C/B 600 series of DC/DC and AC/DC converter modules and battery charger (B600 models) has been announced by Schaefer. 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, telecomms/datacomms, alternative energy, transit/railway, process control and power stations.

The ultra-high efficient series delivers up to 500W of power and offers a DC input voltage range of 10-380VDC with seven input range choices. AC input options include single-phase 115 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 400VDC. 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°C (derate 2.5%/°C from +55°C), with an option for -40 to +75°C.

Modules are housed in an industry-standard 3U form factor for insertion into 19” sub-racks. Optional wall, chassis and DIN-Rail mounting are available. All models feature 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. Mechanical and electrical modifications are readily available.
