Safety products: Schaefer Inc. unveils their Redundant and Dual Redundant Rack Systems for mission critical applications where high-reliability is essential, and loss of power difficult. Applications include but are not limited to CBTC, PTC, signals, controls, substation emergency lighting.
The Redundant and Dual Redundant Systems output power package range from 250W to 5000W in one 19” chassis using Schaefer’s C500 to C4500 Series units (higher power systems available upon request). Output voltages of 24, 48, 60, 100, 110, and 150VDC (additional DC voltages are available) and input voltages 115/230VAC @ 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, extended operating temperature
Mechanical and electrical modifications to standard modules are available upon request. In addition, Schaefer can design and manufacture fully custom solutions.
