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.
