Wall Industries, Inc. 5 Watson Brook Road Exeter, NH 03833 603-778-2300 www.wallindustries.com Fax 603-778-9797 PSRL0402DM Series 400 Watt with Airflow Dual Output Medical Approved AC/DC Medical Power Supply with Active PFC FEATURES ● 2 Year Warranty ● Both Medical & ITE Safety Approvals ● Power Factor Corrected to EN61000-3-2 Class D ● 3.3/ 5/ 12/ 24V Dual Output Optional Combinations ● U-Chassis Type Drive Max 250W Under Air Convection ● U-Chassis & Enclosed with Built-in Fan Mechanical Options ● 1U Height Size and High Power Density: 6.25 Watts/cu Inches SPECIFICATIONS: PSRL0402DM Series All specifications are based on 25 oC, Nominal Input Voltage, and Maximum Output Current unless otherwise noted. We reserve the right to change specifications based on technological advances. INPUT SPECIFICATIONS Input Voltage 90 – 264VAC Full Range Input Frequency 47 to 63Hz Input Current 6.35A at 90VAC full load Inrush Current 35A max @ 230VAC with full load and cold start. Leakage Current Medical degree 300µA; ITE degree 1.5mA. Remote ON/OFF Designated as RSW on the CN3, requires a low signal to inhibit output. OUTPUT SPECIFICATIONS Output Voltage See Table Output Power Range 400 Watts max with airflow. (See Note 4) Output Adjustability Output user adjustable ±5% minimum. Total Regulation ±5% Output Current See Table Ripple & Noise (peak to peak) ±1% Transient Response Returns to within 1% in less than 2.5ms for a 50% load change and the peak transient does not excess 5%. Hold-Up Time 20ms min. at 80% of full load. Overshoot Turn-on/off not exceed 5% over nominal voltage. Turn On Delay 1 second maximum at 120VAC. Remote Sense Designated as RS+ and RS- on the CN3. PROTECTION Over Voltage Protection Latching down will occur when output voltage exceeds 130% and recycle AC input to reset. Short Circuit Protection Trip without damage and auto-recovery. Over-Temperature Protection Protected in the event of excessive operating ambient 85°C and automatic recovery. Over-Power Protection C.C. mode 110-140% and auto-recovery. Input Voltage Protection Power shut down under 80 ±5VAC, and recovered over 86VAC. Input Circuit Protection (Primary) Two T8A/250V fuses inserted. GENERAL SPECIFICATIONS Switching Frequency 30KHz fixed frequency Efficiency 75% minimum (measuring at 230Vand full load). Withstand Voltage 1500 VAC input line to chassis (2mA DC cut off current); 4000VAC between primary and secondary windings. Primary to core 1500VAC. All for 3 seconds. Burn In 45 ±5°C for one hour @ 230VAC with full load. PFC Active power factor correction meets EN61000-3-2 class D. Power Good Designated as PG on the CN3 will go high 100-500ms after regulation and goes low 1ms before loss of regulation. Power Supply On Green LED designated as LED 1 on the PCB. Grounding Test Apply 40A from ground pin to the earthed connection point. Max allowable resistance is 0.1 ohm. LED Display Bi-color green LED in front panel (E Type only). Any protection occurred or RSW applied low signal will emit orange. E Type (Enclosed with built-in Fan): 9(L) x 5(W) x 1.6(H) inches. U Type (U-Chassis Type): 8(L) x 5(W) x 1.6(H) inches. |
