Parameters

VLL, VLN, A (avg & phase wise), Hz, W, VA, PF (avg & phase wise), Wh, Hi-Amps, Load Hours, OLD registry(Wh, L.H.), ON time (non-resettable). Quick & easy navigation & programming. Displays more than 25 parameters

VLL, VLN, A (avg & phase wise), Hz, W, VA, PF (avg & phase wise), Wh, Load Hours, OLD registry (Wh, L.H.). Wh or VAh programmable with 7-digit resolution LCD, 6-digit resolution LED & 4-digit resolution for instantaneous parameters

PF, Wh or VAh, OLD registry, (VLL, VLN, A, Hz) or W or VA – any 2 programmable. Displays more than 15 parameters. 3 row LED display with 6 digits each.

PF, Wh, OLD registry, (VLL, VLN, A, Hz) or W or VA or PF or Wh – any 2 programmable.

Displays programmed parameter’s name and value for instantaneous parameters. Reduces complexity of stocking as this can be used for multiple measurement applications

Wh, (W or VA or PF or Wh) – any 1 programmable. Displays programmed parameter’s name and value for instantaneous parameters. Reduces complexity of stocking as this can be used for multiple measurement applications

Application Information:

LG+ series has optional optically isolated RS485 or pulse O/P which can be integrated into a process through PLC/DCS for online energy management. For pulse O/P, if the DCS/PLC has a self-excited 12V or 24V, external DC supply is not required.
