SPD24RM20

Switching Power Supply Redundant Module Type SPD24RM20 DIN rail mounting • • • • • • • • Product Description This SPD additional module allows the connection of 1 power supply +1 or more additional redundant power supplies. In this case, the continuity of the 24VDC output is always guaranteed, even in case of failure of one power supply. 2 relay outputs provide voltage free outputs in order to send the alarm to a control unit when a failure occurs. Installation on DIN Rail 7.5 or 15mm 2 “Power Rdy” relay outputs Up to 480W output Unlimited number of connectable redundant power supplies Very compact dimensions UL, cUL listed TUV approved Ce and RoHS compliant Ordering Key SP D 24 RM 20 Model Mounting ( D = Din rail ) Output voltage Redundant module Maximum current Approvals au art geprü f t B y p e T d Rheinland Product Safety e appro v Output Data Input Data Output voltage drop Output maximum Current Output Peak Current >5ms Max Reverse Voltage 0.5V 20A 30A 30V Rated input Voltage Number of inputs Maximum input current 21...28VDC 2 20A Controls and Protections Approvals and EMC Power RDY relay Output OK Fail Contact rating Shock resistance input 20...30V ±5% input 20...30V ±5% 1.0A (15G, 11ms, 3 Axis, 6 Faces, 3 times for each Face) Vibration resistance acc. to IEC 60068-2-6 (Mounting by rail: 10-500 Hz, 2G, along X, Y, Z each Axis, 60 min for each Axis) General Data UL / cUL Insulation Voltage Input / Relay contact Insulation Resistance Input / Relay contact @100VDC Operating temperature Storage temperature Relative Humidity MTBF (Bellcore issue 6 @ 40°C, GB) Cooling Case material Dimensions L x W x D Weight 1 acc. to IEC 60068-2-27 100VDC 100MΩ -25°C...+71°C -25°C...+85°C 20...95%RH 659,000h Free air convection Plastic 90 x 54 x 114mm 210g TUV CE UL 508 Listed UL 60950-1 Recognized EN 60950-1, CB scheme EN 55022 Class B, EN 55024, EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-6, EN 61000-4-8, EN 61204-3 Specifications are subject to change without notice.

PS #2 PS #1 SPD24RM20 SPD24RM20 Vin A Vout Load PS #1 Vin B Vin A Vin B SPD24RM20 PS #1 2.) Single Use: Connecting only one PS to one SPD24RM20 to reduce the stress of the diodes and hence increase the reliability. Vout Vout Load 3.) 1+N Redundancy: Using more than one PS as redundant units to increase the reliability.
