Energy management: Schaefer Inc. introduces the C/B3500 Series of 850 Watt DC-DC and AC-DC converter modules and battery charger. Using industrial grade components, the compact and robust 6U design provides a highly efficient, space-saving solution for the most extreme environments including a variety of onboard (74VDC to 110 or 24VDC) and wayside installations (115VAC to 12 or 24VDC). Other industrial applications include military, transportation, alternative energy, and process control systems.

The highly efficient C3500 converters are available in seven standard DC input voltage ranges from 18VDC up to 640VDC. AC input options are single-phase 115VAC or 230VAC (with or without PFC) or three-phase inputs of 3x200, 3x400 and 3x480VAC. Single outputs are available in twelve standard ranges encompassing 5VDC-400VDC. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).

The C3500 has comprehensive protection circuitry and efficiencies are up to 92%. Safety and construction standards meet both EN 60950-1 and EN 50178. EMI according to EN 61000-6-4, Class A (optional Class B upon request). 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. DC-DC and AC-DC models have remote sense capability. Options include increased mechanical strength, tropical protection, extended operating temperature, input diode, input MOV (600+ VDC), active current sharing interrupt.

Mechanical and electrical modifications to standard modules are available upon request. In addition, Schaefer can design and manufacture fully custom solutions.
