This test board from Artesyn Embedded Power is specifically designed for the DS650 and DS850 series of power supplies. It facilitates testing and servicing of these distributed power bulk front-end units.
The board features a compact 1U x 2U form factor, making it suitable for integration into standard rack systems. Key electrical and communication features include an I2C interface for FRU EEPROM data access and an amber/green bi-color LED status indicator. The power supplies themselves operate from a Telco style -39 V to -72 VDC input range and provide a +12 Vdc main output with a +3.3 Vdc standby output.
Standard features of the associated power supplies, which this test board supports, include active current sharing, internal ORing FETs, and hot-plug operation. The test board aids in managing these functionalities during development and field maintenance.
The input voltage range is -40 Vdc to -75 Vdc.
The DS650DC provides +12 Vdc at 70 A, and the DS850DC provides +12 Vdc at 52.5 A.
The standby output is +3.3 Vdc at 6A, with an optional +5 Vdc at 4A available.
The series is certified with UL/cUL 60950 (UL recognized), NEMKO+ CB report EN60950, CE mark, and China CCC.
An I2C communication interface bus is provided for FRU EEPROM data.
