PBA50F-24
COSEL PBA50F-24 PBA series 50 W AC-DC enclosed supply, universal 85-264 VAC input, 24 V output and convection cooling.
The PBA50F-24 is a COSEL PBA series enclosed AC-DC power supply rated at 50 W with a universal input of about 85 V to 264 V AC (or 120 V to 370 V DC on the same terminal) and a single regulated 24 V output, in a compact enclosed chassis. It is a general-purpose industrial supply from a long-established COSEL range, and it provides an adjustable output, an operating LED and protection for over-current and over-voltage, with an isolation of about 3 kV between the input and the output. The unit cools by convection, so it suits a sealed or a quiet enclosure, and the operating temperature range covers about -10 °C to +71 °C with the standard derating. The PBA series includes a harmonic attenuator that meets the IEC 61000-3-2 power-factor requirement, so the input current is well behaved, and the rugged construction suits an industrial control panel, a test bench or a small machine. Typical applications include industrial automation, control panels, test and measurement and a small medical or telecom unit. Every supply BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you size the power and plan the derating and the EMC filtering.
FAE Professional Review
The PBA50F-24 is a compact 50 W supply for a panel or a bench, with a universal input, a 24 V output and convection cooling, so it fits a sealed enclosure. Add an EMI filter at the input for the conducted emissions and confirm the derating at the highest ambient. It is a simple, rugged choice for a low-power industrial load.

Frequently Asked Questions
What projects suit the PBA50F-24?
It suits a low-power industrial load that needs a 24 V rail from the mains in a compact, convection-cooled enclosure, such as a control panel, a bench instrument or a small machine.
Confirm the load and the derating.
Do I need an EMI filter?
A switching supply reflects conducted noise onto the mains, so a COSEL EMI filter such as the NAC-10-472 at the input helps the equipment meet the emissions limit. Choose the filter current above the load and the leakage for the application.
Our FAE team can help choose the filter.
Is the supply genuine and documented?
BeiLuo supplies factory-traceable PBA50F-24 supplies with an import declaration, certificate of origin and RoHS file on every order. Stock is normally available and the datasheet downloads from this page.
