Siemens 538-993 Digital Energy Monitor 2000 100A Pre owned/ good condition/ pulled from working environment The Siemens 538-993 is a Digital Energy Monitor (DEM), Electrical Series 2000, with a small split?core current transformer (CT) for 100 A, designed to measure 1? or 3?phase electrical loads and communicate energy data over a Siemens APOGEE Floor Level Network (FLN) Part 538-993 is listed as a Digital Energy Monitor, Series 2000, small CT, split?core, 1 or 3?phase, 100 A, 50/60 Hz. It belongs to the Series 2000 DEM family, which are digital power transducers integrating a communicating microprocessor and split?core CTs in one package. What it measures / does Measures three?phase consumption (kWh), demand (kW), and power diagnostics such as kVA, kVAR, power factor, volts, and amps, depending on DEM 1000 vs DEM 2000 model features. Provides continuous accumulation of kWh and retains consumption values through power outages. Uses split?core, volt?signal CTs which are inherently safer and accurate to 1% (ANSI C12.1 metering standard). Electrical and installation details (Series 1000/2000) Voltage input range: 208?480 Vac, three?phase Delta or Wye (277/480 or 120/208 systems); also suitable for certain single?phase configurations.? Frequency: 50/60 Hz. Maximum primary current: for the 538?993 model, 100 A with a small split?core CT. Environmental: operating 32F to 140F (0?60C), up to 90% RH non?condensing. Networking / system integration Connects directly to a Siemens APOGEE Floor Level Network (FLN) as a field device, alongside other FLN controllers. Uses a 3?pin removable terminal block for FLN connection and has DIP switches to set the FLN address plus a bi?color status LED for normal/fault indication. We are wholesaler/liquidators.
