The Cincon CQB50W8-36S28-CMFC is a 50-watt, isolated DC-DC converter from the CQB50W8 series. It operates with a wide input voltage range of 9.5 to 75 VDC, nominal at 36 VDC, and provides a regulated 28 VDC output at up to 1.79 A.
Key features include up to 90% efficiency, fixed switching frequency, regulated outputs, and remote On/Off control. The converter is fully protected against over-temperature (OTP), over-current (OCP), over-voltage (OVP), and under-voltage lockout (UVLO). It offers 3000 Vac I/O isolation and operates within a case temperature range of -40 to +105°C.
Designed for chassis mounting with a baseplate cooled mechanism, this open-frame converter is suitable for applications requiring robust performance and compliance with standards such as UL62368-1, EN50155 for EMC and environmental characteristics, and EN45545-2 for fire and smoke safety. It also includes a built-in EMI filter.
This model is compliant with RoHS3 standards and has an MSL of 1. Its dimensions are 116.8mm x 61.0mm x 32.0mm.
