VRA.00333.0

The Bel Power Solutions VRA.00333.0 is an evaluation board specifically designed for the PET1300-12-054NA power supply. This AC to DC power supply converts standard AC mains power into a 12 VDC output, suitable for powering intermediate bus architectures in high-performance servers, routers, and network switches.

The PET1300-12-054xA, for which this is an evaluation board, offers a high efficiency of up to 94.0% and operates with a wide input voltage range of 90 – 264 VAC. It features active power factor correction and an always-on 10W standby output at 3.3V. The design supports hot-plug capability and parallel operation with active current sharing. Full digital control is implemented for circuit loop and power management, contributing to a high density design of 30.25 W/in3 within a compact form factor of 54.5 x 40.0 x 321.5 mm.

This evaluation board facilitates testing and integration of the PET1300-12-054xA power supply. The power supply itself meets international safety standards, including UL/CSA 62368-1 and IEC / EN 62368-1, and displays the CE-Mark for the European Low Voltage Directive (LVD). It includes comprehensive protection features such as Over-Temperature Protection (OTP), Over-Current Protection (OCP), Over-Voltage Protection (OVP), and Short-Circuit Protection (SCP). A PMBus communication interface is provided for control, programming, and monitoring, along with 4K Bytes of EEPROM for user information. Status is indicated by two LEDs: FAIL and OK.

The evaluation board is packaged in bulk and is RoHS3 compliant. It is intended for use in applications such as high-performance servers, networking switches, and routers.
