  • Page 15 Relay Output Terminals. Auxiliary Power Supply: The AcuRev 1312 power meter requires an AC supply of 100-415V at 60Hz for operation. In nor- mal operation, the power consumption of the meter is less than 1 Watt so the meter can be powered by either an independent power supply or it can obtained from the circuit under test.
  • Page 16 The meter requires AWG22-14 as the wires to connect the power supply. Voltage Input: The AcuRev 1312 can measure up to 240V LN/415V LL AC for a three phase system or 400VLN AC for a single phase system. Potential Transformers (PT’s) must be used when the system voltage is higher than the meter’s rated voltage.
