Rack systems are suited for mission critical applications
Designed for mission critical applications where high-reliability is essential and loss of power difficult, Schaefer has announced redundant and dual redundant rack systems. The systems output power from 250 to 5,000W in one 19” chassis using Schaefer’s C500 to C4500 series units (higher power systems available upon request).
Applications include but are not limited to CBTC, PTC, signals, controls and substation emergency lighting.
The redundant and dual redundant rack systems output voltages of 24, 48, 60, 100, 110 and 150VDC (additional DC voltages are available) and accept input voltages 115/230VAC at 50/60Hz single phase (3-phase AC and DC voltages available). Typical installation options include decoupling diode, DC-OK with relay, series diode (reverse polarity protection), current sharing/interrupt, inrush current limiting, increased mechanical strength, tropical protection and extended operating temperature.
Mechanical and electrical modifications to standard modules are available upon request. Schaefer can also design and manufacture fully custom solutions.
