DESCRIPTION

The CQB150-300S24 is a 150-watt isolated DC-DC converter designed for industrial applications requiring high reliability and wide input voltage range. It features a 2:1 input voltage range of 180-425V DC with a regulated 24V output capable of delivering up to 6.25A at full load, achieving 88.5% efficiency. The converter incorporates comprehensive protection mechanisms including over-temperature protection (OTP), over-current protection (OCP), over-voltage protection (OVP), and under-voltage lockout (UVLO), with 3000Vac input-to-output isolation. Operating across a case temperature range of -40°C to +105°C in a compact quarter-brick form factor (2.28" × 1.45" × 0.5"), it meets stringent industrial standards including IEC/EN/UL 62368-1 reinforced insulation approval and MIL-STD-810F shock and vibration compliance. This converter is ideal for telecommunications, industrial control systems, and railway applications where robust power conversion with high isolation and protection is essential.
