D E U N I T N O C 400 WATT DIS Product Data Sheet AC/DC POWER SUPPLY SX400 FEATURES DESCRIPTION z Active Power Factor Correction The SX400 is a compact 400 watt Power Factor Corrected, single output power supply. Active current sharing circuitry with ORing diodes, together with control functions and alarm options, simplifies N+1 and redundant applications. z Active Current Sharing With ORing Diodes z FCC/VDE Class B EMI Filter z Optional Active Inrush Current Limit z Compact Size: 10” x 4.85” x 2.19” z Optional SCR Crowbar z Optional Cover With Fan AGENCY APPROVALS See “Safety” section on page 2 for more information 3400 E Britannia Drive • Tucson, Arizona 85706 • Phone: 520.295.4100 • Fax: 520.770.9369 • Internet: http://www.cdpowerelectronics.com SX400 2/98 REV A Page 1 Input Specifications Parameter Conditions Operating Range Min 47-63 Hz Typ 90 Max Units 264 VAC 30 APK 60 APK Inrush Current Limiting Thermistor 120 VAC, cold start 240 VAC, cold start Active Current Limit 264 VAC Efficiency Nominal line and full load Power Factor Correction (PFC) 19 APK 75 % 0.99 Meets IEC 1000-4-7/EN61000-3-2 (formerly IEC 555-2) Remote Sense Remote Sense is provided and will compensate for 1.0V of line drop. Remote Sense leads are protected against open, short and reversal. Power Fail Signal Upon AC input voltage removal, the power fail signal drops to logic zero at least 10msec before loss of DC output. Upon AC input turn-on, signal remains low until output is in regulation. Consult the factory for other options. Remote On/Off (Optional) The power supply is turned on with a TTL logic ‘1’ (or open) signal and turned off by a switch closure or TTL logic ‘0’ referenced to (-) sense terminal. Consult the factory for other options. N+1 Load Share Output has active load sharing circuitry. Units will load share within 1% of the Maximum Rated Load. Over Voltage Protection Output #1: 15% of nominal voltage is typical. The power supply will latch off until AC power is cycled. Over Current Protection Automatic recovery upon fault removal. Transient Response The peak output voltage excursion will not exceed 2% and will recover within 1% in 200 μsec for a 25% step load. Reverse Voltage Protection The output is protected to rated load. Page 2 Over Temperature Protection Thermal switch turns off power supply if overheating occurs and automatically restarts. Safety UL Recognized: UL File Number E13164 (1950) CSA Certified: CSA File Number LR 9070C (C22.2 No950, Level 6) TUV License Number: R9773309 (EN60950) (IEC950) Cooling The unit is designed to operate with 30 CFM of airflow. DC Power Good Signal The signal is activated by a ±10% loss of regulation Active low or high; TTL Level; common with (-) sense. Consult the factory for other options.
