T t y f p e r p e a g p Switching Power Supply Redundant Module Type SPD24RM20 DIN rail mounting 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 *The power supplies can be externally connected with SPD24RM20 to increase the output power. However it is suggested to use 90% load only, for example 10A*2*0.9= 18A. The power supplies of different models or spec. can not be connected for parallel operation. Product Descrip tion Ordering Key SP D 24 RM 20 This SPD additional module is always guaranteed, even in Model allows the connection of case of failure of one power Mounting ( D = Din rail ) 1 power supply +1 or more supply. 2 relay outputs provide Output voltage additional redundant power voltage free outputs in order Redundant module supplies. In this case, the to send the alarm to a control Maximum current continuity of the 24VDC output unit when a failure occurs.
