The TDK Corporation JFS0500-24 is an enclosed AC/DC converter designed for industrial applications. It delivers 500W of power with a nominal output of 24V and a current rating of 20.8A.
Key electrical specifications include a wide AC input voltage range of 85-265VAC and a typical efficiency of 75% at 110VAC. The unit incorporates Power Factor Correction (PFC) meeting EN61000-3-2 standards, with a typical power factor of 0.99. It offers overcurrent and overvoltage protection with auto-recovery, and a hold-up time of 16ms.
Designed for flexibility, the JFS0500-24 supports remote sense and remote adjustment via external resistor or voltage. It also features remote on/off control and provides open-collector signals for AC fail and DC good status. The converter is built for chassis mounting and operates within a temperature range of -20°C to +70°C, with derating applied above 50°C.
Safety and compliance are addressed with UL508, UL60950, CSA22.2 No.60950, EN60950, FM3611, and CE Mark approvals. It also meets EN55022 Class A and FCC Docket 20780 Part 15, Subpart J, Class A for conducted and radiated EMI. The product comes with a 5-year warranty.
The AC input range is 85-265VAC (47-63Hz) and the DC input range is 120-330VDC.
The output is 24V DC at 20.8A, providing 500W.
The operating temperature range is -20°C to +70°C with linear derating to 50% load from 50°C.
It includes overcurrent protection (<110% auto recovery) and overvoltage protection (30V for 24V models, 60V for 48V models).
Yes, it supports remote sense (compensates for 0.25V drop per leg), remote adjust (via external resistor or voltage), and remote on/off (low = OFF, open = ON).
Yes, they can be paralleled using single-wire current sharing.
Typical efficiency is 75% at 110VAC input.
