Output regulation includes line & load. 2. Ripple & noise is measured from 10 Hz to 20 MHz. Connection to the unit is made with a 0.1 µF ceramic capacitor & a 22 µF electrolytic capacitor connected in parallel. 3. A 1% minimum load is required to maintain regulation & ripple specifications. 4. Transient recovery is measured to within a 1% error band for a load step of 50% to 100%. 5. Isolation specifications are production HI-Pot tested for 3 seconds. 6. The full output range (see table) is covered in the safety agency certification. Standard models are factory set to the Preset voltage, but may be set to other levels within the range without affecting the agency certification. For more information, contact the factory. 7. Output power is given for the factory preset voltage. The maximum continuous output power level is 150W without providing 25 CFM airflow. All models provide a peak power level of 600W for a maximum duration of 500 µS. For more information, contact the factory. 8. Each unit includes two 250V/5A fuses. Since these fuses are not field replaceable, it is recommended that an external fuse of the same size be used on the input of the power supply for protection. Models with other output voltage levels are available (i.e. 36 VDC, etc) Contact the factory for details at: [email protected] Mechanical Dimensions Connections Input Connector (CN1): • Terminal Block: Howder HD-601-3P 3 pins, 6.35 mm Centers • Molex Mating Part No: Molex 035977-0500 or equivalent (two pins removed) Pin Function 1 2 3 AC-Line AC-Neutral Field Ground Logic Signal Connector (CN3): • Mating Part No: JST XHP-4 or equivalent (CHYAO SHIUNN JS-2001-04) • Mating Pins: JST SXH-002T-PO.6 For AWG 30 to 26 Output Connector (CN2): • Terminal Block (Must be used on 12 VOUT): Dinkle P-830N M5 Screws • Molex Mating Part No: Molex 035977-0600 or equivalent Pin Molex Pin Dinkle Pin Function 1 2 3 4 5 6 -VOUT -VOUT -VOUT +VOUT +VOUT +VOUT 1 2 -VOUT +VOUT 1 2 3 4 Remote On/Off Fan Fail Common Power Good MicroPower Direct Fan Driver Connector (CN4): • Mating Part No: JST XHP-3 or equivalent (CHYAO SHIUNN JS-2001-03) 3 Pins 0.98 Pitch Pin Function 1 2 3 Fan Fail Minus Plus Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.02 (±0.50) We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • FAX: (781) 344-8481 • E-Mail: [email protected]
