Cincon CQB75W14 75W 14:1 Input Isolated DC-DC Converters

Cincon CQB75W14 Input Isolated DC-DC Converters deliver 75W output power at single output voltages of 5VDC, 12VDC, 15VDC, 24VDC, 28VDC, and 54VDC. These converters come in an industry-standard quarter-brick package and feature an ultra-wide 14:1 input voltage range of 12VDC to 160VDC (72VDC nominal) and 3000VAC reinforced isolation. Additional features include high efficiency up to 91%, remote on/off, and -40°C to +105°C case operating temperature range. The low no-load power consumption of 20mA makes these units an ideal solution for energy-critical systems. Cincon CQB75W14 Input Isolated DC-DC Converters are fully protected against input undervoltage lockout (UVLO), output overcurrent (OCP), output overvoltage (OVP), overtemperature (OTP), and continuous short-circuit conditions. The series is compliant with EN 50155, EN 45545, and EN 50121-3-2.

The CQB75W14 DC-DC converters are designed primarily for common railway applications of 24V, 36V, 48V, 72V, 96V, and 110V nominal voltage. This series is also suitable for distributed power architectures, telecommunications, battery-operated equipment, and industrial applications.
