As an EPSM Group 1 (EPSMG1) board, it converts a 125 VDC input feed from the power distribution module into regulated internal control voltages (+5 VDC, +\/-15 VDC, +24 VDC) and external subsystem drives (+\/-24 VDC, isolated +70 VDC). The module features a two-stage conversion topology with a buck regulator and push-pull inverter, driving trip solenoids rated at 125 VDC and interfacing through the Exciter Power Backplane (EPB).\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eIS200EPSMG1AED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric (GE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e17.8 cm x 33.02 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e125 VDC input feed conversion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eEX2100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eExciter Power Supply Module (EPSMG1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConversion Topology\u003c\/td\u003e\n\u003ctd\u003eBuck regulator and push-pull inverter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInternal Output Voltages\u003c\/td\u003e\n\u003ctd\u003e+5 VDC, +\/-15 VDC, +24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Output Voltages\u003c\/td\u003e\n\u003ctd\u003e+\/-24 VDC, isolated +70 VDC (contact wetting)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTrip Solenoid Channels\u003c\/td\u003e\n\u003ctd\u003e3 channels (rated at 125 VDC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAnalog Voltage Inputs\u003c\/td\u003e\n\u003ctd\u003e6 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Voltage Range\u003c\/td\u003e\n\u003ctd\u003e+\/-5 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCircuit Assembly\u003c\/td\u003e\n\u003ctd\u003eSurface Mount Technology (SMT)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eI\/O Density Scaling and Backplane Power Distribution\u003c\/h3\u003e\n\u003cp\u003eThe IS200EPSMG1AED optimizes I\/O density scaling across EX2100 control cabinets by consolidating dual-stage power regulation and 125 VDC trip solenoid drive channels onto a single 17.8 cm x 33.02 cm surface-mount assembly. By routing multi-rail outputs (+5 VDC, +\/-15 VDC, +24 VDC, and isolated +70 VDC) directly through P1 and P2 backplane headers to the Exciter Power Backplane (EPB), the module supplies power to M1, M2, and C controllers simultaneously without requiring secondary external power converter chassis.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What is the primary operational difference between EPSMG1 and EPSMG2 modules?\u003c\/p\u003e\n\u003cp\u003eA: EPSMG1 modules, such as the IS200EPSMG1AED, are configured specifically for excitation control systems powering M1, M2, and C controllers, whereas EPSMG2 modules are designed for regulator control and integrate an auxiliary daughterboard.\u003c\/p\u003e\n\u003cp\u003eQ: What internal power conversion architecture is utilized on the IS200EPSMG1AED?\u003c\/p\u003e\n\u003cp\u003eA: The board utilizes a two-stage conversion topology consisting of an initial buck-regulator stage followed by a push-pull inverter stage to step down the 125 VDC input feed.\u003c\/p\u003e\n\u003cp\u003eQ: Which external subsystems receive power drives from the IS200EPSMG1AED board?\u003c\/p\u003e\n\u003cp\u003eA: The board delivers +\/-24 VDC to system fans, de-excitation modules, crowbar modules, ground detector modules, and field voltage\/current modules, alongside an isolated +70 VDC supply for terminal board contact wetting.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize and lock out the main 125 VDC input supply feed from the power distribution module before installing or removing the board.\u003c\/li\u003e\n\u003cli\u003eAttach an electrostatic discharge (ESD) grounding wrist strap to a bare metal enclosure ground prior to touching module components.\u003c\/li\u003e\n\u003cli\u003eAlign the 17.8 cm x 33.02 cm circuit board with the mounting guide slots on the Exciter Power Backplane (EPB).\u003c\/li\u003e\n\u003cli\u003eSeat connectors P1 and P2 firmly into the backplane headers, ensuring full mechanical engagement before tightening retaining screws.\u003c\/li\u003e\n\u003cli\u003eVerify field cable routing and shield grounding for external power outputs (+\/-24 VDC and +70 VDC) to prevent common-mode voltage noise coupling.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":43846555107418,"sku":"IS200EPSMG1AED","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/IS200EPSMG1AED.jpg?v=1786699230","url":"https:\/\/www.spareoil.com\/products\/ge-is200epsmg1aed-ex2100-exciter-power-supply-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
