The Artesyn Embedded Power DS850-9 is a distributed power bulk front-end AC DC converter rated at 850 watts. It accepts a universal input voltage range of 90 to 264 VAC and provides a main DC output of +12VDC at 52.5A, along with a +3.3Vsb standby output. This power supply is designed for ITE (Commercial) applications and features a 1U x 2U form factor suitable for rack mounting.
Key features include hot-plug operation, N+1 redundancy, internal ORing FETs, and active current sharing for reliable system operation. It also incorporates an I²C communication interface for FRU data and an EEPROM for service data storage, facilitating efficient field replacement. The unit includes a built-in cooling fan with speed control and a fan fail tach output signal for monitoring.
Electrical specifications include an efficiency greater than 80% typical, conducted and radiated EMI compliant with FCC Subpart J EN55022 Class B, and a hold-up time of 1 ms at 48 Vdc. Overcurrent, overvoltage, and undervoltage protections are integrated to safeguard the system. Logic control signals such as PS_SEATED, PWR GOOD, DC Input OK, Temp OK, and PS_INHIBIT/PS_KILL are provided for system integration.
The main DC output voltage is +12 VDC at 52.5 A for the DS850DC model.
