Embedded power supply 45W 48V 1A EPS-45-48-C

Switching power supply for built-in applications – a reliable energy source

The EPS-45-48-C power supply is an open-frame switching power supply designed for installation in devices requiring a stable 48V DC voltage. It is ideal for industrial automation applications, monitoring systems, powering electronic devices, and anywhere where compact size and high efficiency are important. The *open frame* design simplifies integration of the power supply inside the device housing, minimizing space usage.

### Characteristics and application

The power supply from the EPS series is characterized by high efficiency (up to 90% depending on the load) and low power consumption in no-load condition (below 0.3W), which translates into energy savings. Designed to operate in a wide temperature range (-30°C to +70°C), it ensures reliable operation even in harsh environmental conditions. This makes it a suitable solution for both indoor and outdoor installations, protected from direct exposure to the elements.
