Bel Power Solutions RQB-100Y 100W Isolated DC-DC Converters

Bel Power Solutions RQB-100Y 100W Isolated DC-DC Converters are high-performance devices specifically designed for railway applications and associated equipment. The RQB-100Y DC-DC Converters offer a 100W single output voltage, a wide 14V_DC to 160V_DC input voltage range, and a -40°C to +105°C operating temperature range. Protections include input undervoltage, output overvoltage, overcurrent, short circuit, and overtemperature. Bel Power Solutions RQB-100Y 100W Isolated DC-DC Converters also feature remote on/off control, remote sense compensation, programmable undervoltage lockout, hold-up function, and output voltage trim adjustment.
