certification. Models are factory set to the "Preset" voltage. This may be adjusted within Notes: the range without affecting the agency certification. Contact the factory for details. 1. Output regulation includes line & load. 6. Output current is given for the factory preset voltage. With the exception of the "05" 2. Ripple & noise is measured from 10 Hz to 20 MHz. Measurement output model, the maximum continuous output power level is 320W (with 28.5 CFM), connection to the unit is made with a 0.1 F ceramic capacitor & a 22 180W (U-Chassis convection cooled) or 170W ("C" units convection cooled. For more F electrolytic capacitor connected in parallel. information, contact the factory. 3. Transient recovery is measured to within a 1% error band for a load 7. Units will provide peak power of 700W for 500 S. For units capable of longer durations, step change of 50% to 100%. contact the factory. 4. Isolation specifications are production HI-Pot tested for 3 seconds. 5. The full output range (see table above) is covered in the safety agency 8. A 1% minimum load is required to maintain regulation and ripple specifications.
Logic Signal Connector CN1: Mating JST XHP or equivalent (CHYAO SHIUNN JS-21001-3) Mating Pins: JST SXH-002T-P0.6 for AWG 30 to 26. Fan driver connector (FAN2): 12 VDC / 400 mA is available to drive an external fan. Mating connector is a JST XHP-2 or Molex P/N 48-151-0210 ( 2 pins 0.98 pitch). Mating Pins: JST SXH-001TP0.62T or Molex 48150 .
