CQB50W12 Series: 30 W to 50 W 12:1 Input Isolated DC/DC Converter

Cincon's CQB50W12 series converters are updated to IEC/UL 62368-1, the safety standard for information and communication technology (ICT) and audio/video (A/V) equipment. The CQB50W12 series of DC-DC converters offers 30 W to 50 W of output power at single output voltages of 5 V_DC, 12 V_DC, 24 V_DC, and 48 V_DC with industry standard quarter-brick. It has a wide (12:1) input voltage range of 14 V_DC to 160 V_DC (72 V_DC nominal) and 3000 V_DC basic isolation.

The CQB50W12 is compliant with EN50155, EN45545, and EN50121-3-2. They feature high efficiency up to 89%, allowing case operating temperature range of -40°C to +100°C. An optional heat sink is available to extend the full power range of the unit. Very low no load power consumption (5 mA) is an ideal solution for energy critical systems. The standard control functions include remote on/off (positive or negative) and +10%, -20% adjustable output voltage.

These converters are fully protected against input undervoltage lockout (UVLO), output overcurrent, output overvoltage, overtemperature, and continuous short circuit conditions. CQB50W12 series is designed primarily for common railway applications of 24 V, 36 V, 48 V, 72 V, 96 V, and 110 V nominal voltage and is also suitable for distributed power architectures, telecommunications, battery-operated equipment, and industrial applications.
