EFFICIENCY (Nominal line, full load): CRP340K1 of 82% minimum. CRP340L1 of 83% minimum. POWERFACTOR AND HARMONIC CORRECTION: Compliant to EN61000-3-2 down to 10% load. Power factor 0.99% typical at full load.

OUTPUT SPECIFICATIONS
TOTAL PACKAGE OUTPUT POWER: Full power from 0°C to 50°C. Derate 2.5% / °C to 50% at 70°C. See “Standard Models” section above. OUTPUT RATINGS: See “Standard Models” section above. SELF-LIMITING & SELF-PROTECTING: Automatically limits output power to compensatefor elevated temperature up to 70°C ambient. CURRENT LIMITING: Constant current at 110% of continuous output current rating. Output recovers when fault is removed. Maximum output current under any conditions will not exceed Io maximum ratings x 1.33. SHORT CIRCUIT OUTPUT CURRENT: Maximum of the output current rating x 1.33. REGULATION TOTAL (Line, Load & Initial Setting): With or withoutisolation diode at remote sense point, ±0.5%, from 0 to full load. TURN ON TIME: 2 seconds maximum (before Current Walk In time).

INPUT SPECIFICATIONS
INPUT VOLTAGE RANGE: 85-265VAC Continuous Range operation from 47-63 Hz. Internally fused with a 6.3A 250VAC, 5x20mm, Axial FA Type. Leakage: 3 ma max. Input Frequency Transient: 47-400Hz per Bellcore TR-TSY000947. UNDER VOLTAGE PROTECTION: On at 80±5V. Off at 75 ±5V. INRUSH CURRENT: 15 amps maximum.

CURRENT WALK IN: 8 to 16 seconds from 0 to 90% load (Per Bellcore).

OUTPUT SPECIFICATIONS (CONT’D)
TEMPERATURE COEFFICIENT: ±0.02% / °C. VOLTAGE DRIFT: 0.1% max. for any 8 hour period.OUTPUT VOLTAGE ADJUSTMENT: Pot adjustable. Available from outside of the supply. REMOTE SENSE: Compensates for total line loss of 5%. The output voltage will change by 2% max. should the sense line open. CURRENT SHARING: ±5%. Single Wire Method, shares as a percent of the maximum output current rating. DYNAMIC RESPONSE: 5% step load 10 to 90% recovery in 4 msec . HOLD-UP TIME: At full load, lowline, output will remain in regulation for a minimum of 30 msec after loss of AC input power. OVERSHOOT & UNDERSHOOT: Following turn-On/Off or (Enable/ Inhibit), the output voltage overshoot or undershoot shall be less than 2% of nominal output voltage. THERMAL SHUTDOWN: Shuts down when excessive temperature condition occurs. Recovers when fault is removed. OVERVOLTAGE PROTECTION: CRP340K: OVP...
