Utility supplies: 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 ultra-high efficient C/B 600 Series delivers up to 500W of power and offers DC input voltage range of 10-380VDC 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 5-400VDC. 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°C to +75°C (derate 2.5%/°C from +55°C), with an option for -40°C to +75°C.
Modules are housed in an industry-standard 3U form factor for insertion into 19 in. 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. Mechanical and electrical modifications are readily available.
