Description

1 EACH - SWITCHMODE POWER SUPPLY (PSPLY-SMPS-HP-030) • Cooling: Direct Water • AC Input: 480 Volts, 3 Phase, 60Hz • DC Output: 15 Volts, 3000 Amperes • Ripple: Filtered. The proposed rectifier will maintain imposed AC RMS ripple to less than 2% of full scale voltage output through the rectifier’s entire operating range (10-100% output) • Controls: Integral console with Dynapower’s exclusive Touchpad controller (see Technical Description for full functionality) • Interface: Connections for reference and feedback of voltage and current via digital signals over Ethernet • Enclosure Rating: NEMA 4X

2 EACH – SWITCHMODE POWER SUPPLY (PSPLY-SMPS-R-011) • Cooling: Forced Air • AC Input: 120 Volts +/-5%, 1 Phase, 60Hz+/-2% • DC Output: 12 Volts, 50 Amps • Ripple: Filtered. The proposed rectifier will maintain imposed AC RMS ripple to less than 2% of full scale voltage output through the rectifier’s entire operating range (10-100% output) • Controls: Standard integral controls on/off switch, digital LCD DC voltage and ammeter, and up/down current and voltage control push buttons. • Interface: Signal Isolators for reference and feedback of voltage and current via 4-20mA analog signals • Enclosure Rating: NEMA 1

3 EACH – SWITCHMODE POWER SUPPLY (PSPLY-SMPS-R-013) • Cooling: Forced Air • AC Input: 120 Volts +/-5%, 1 Phase, 60Hz+/-2% • DC Output: 12 Volts, 100 Amps • Ripple: Filtered. The proposed rectifier will maintain imposed AC RMS ripple to less than 2% of full scale voltage output through the rectifier’s entire operating range (10-100% output) • Controls: Standard integral controls on/off switch, digital LCD DC voltage and ammeter, and up/down current and voltage control push buttons • Interface: Signal Isolators for reference and feedback of voltage and current via 4-20mA analog signals • Enclosure Rating: NEMA 1
