1 KEPCO RCW POWER SUPPLIES With Kepco RCW Power Supplies, you re always in great Put them through a shape. real workout.

2 These Heavy Duty RCW Power Supplies can take anything. The RCW are the latest in a long line of single-output, industrial grade switchers from Kepco that pack the power you need for every application. Available in 5 sizes, 100, 175, 350, 750 and 1500 watts, these models incorporate advanced power factor-corrected wide range input technology. In the W models, an EMI filter is built in to ensure that the conducted EMI meets the FCC Class A limit. The 100 and 175W models meet FCC Class B and VDE 0871 Class B. Construction conforms to EN (TÜV) as well as UL 1950 and CSA C22.2 No. 234, level 5. The power factor correction circuit ensures that current is drawn over the entire mains cycle to meet the harmonic current limit of EN and EN Data subject to change without notice Kepco, Inc. Litho in USA FEATURES Wide range a-c input (85-264V a-c). 350W and 1500W (not 750W) models have current sharing for N+1 paralleling. Overcurrent limiter, square type. Undervoltage detector, (350W~1500W models) shuts down RCW if overload persists for more than 40 seconds. Overvoltage protector - immediate shutdown (reset by removing mains power for 40 seconds). Trimmable output voltage. Remote on/off logic. Alarm flags; OV, UV, thermal, fan (350W~1500W models). Power fail alarm (input power failure) (350W~1500W models). Output overvoltage and thermal protection indicator (red) (350W~1500W models). Output low voltage indication (red) (350W~1500W models). Fan alarm indication (red) (350W~1500W models). Remote error sensing: 0.15V for 3.3V models, 0.25V for 5.0V models, 0.4V for 12-48V models. UL/CSA/TÜV safety approval EN W: FCC Class B; W: FCC Class A and VDE 0871 Class B, EMI filter. Certified per MIL STD 810E.
