Output regulation includes line & load. 2. Ripple & noise is measured from 10 kHz 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 135W without providing 16 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 an input fuse (250V/8A). Since this fuse is 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. 5 VDC, 48 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 09-91-0500 or equivalent (two pins removed) Pin Function 1 2 3 AC-Line AC-Neutral Field Ground Output Connector (CN2): • Terminal Block: Howder HD-601-4P 4 pins, 6.35 mm Centers • Molex Mating Part No: Molex 09-91-0600 or equivalent Pin Molex 1 2 3 4 5 6 +VOUT +VOUT +VOUT -VOUT -VOUT -VOUT Pin Howder 1 2 3 4 +VOUT +VOUT -VOUT -VOUT Logic Signal Connector (CN3): • Mating Part No: JST XHP-3 or equivalent (CHYAO SHIUNN JS-2001-03) • Mating Pins: JST SXH-002T-PO.6 For AWG 30 to 26 U-Chassis Cover (C Suffix) Pin Function 1 2 3 Power Good Remote On/Off Common Fan Driver Connector (CN4): • Mating Part No: JST XHP-2 or equivalent (CHYAO SHIUNN JS-2001-2) MicroPower Direct We Power Your Success - For Less! 292 Page Street Ste D Stoughton, MA 02072 • TEL: (781) 344-8226 • Pin Function 1 2 Minus Plus Notes: • All dimensions are typical in inches (mm) • Tolerance x.xx = ±0.02 (±0.50) FAX: (781) 344-8481 • E-Mail: [email protected]
