Dual Panel Mode I
Application:
This configuration applies to systems with a
Single Mains
that are split into two Panels. Branches A and
B belong to Mains-I while Branches C and D belong to Mains-II, as illustrated in the diagram below.
Mains-I and Mains-II are used to measure electrical parameters for Panel-I and Panel-II, respectively.
V1 = Mains-I Voltage Inputs
I1 = Mains-I Current Inputs
V2 = Optional (may be used to measure the ULL Inputs before the Isolation Transformer)
I2 = Mains-II Current Inputs
Power Calculation:
Mains-I Power = V1 × I1 (Wye)
Mains-II Power = V1 × I2 (Wye)
Branch Power = V1 × Branch Current A/B/C/D

Dual Panel Mode II
Application
:
This configuration allows a single PMC-592 to monitor two independent PDU panels simultaneously
and makes the PMC-592 the most economical product in the market.
V1 = Mains-I Voltage Inputs
I1 = Mains-I Current Inputs
V2 = Mains-II Voltage Inputs
I2 = Mains-II Current Inputs
Power Calculation
Mains-I Power = V1 × I1 (Wye, Delta or 1P3W)
Mains-II Power = V2 × I2 (Wye, Delta or 1P3W)
Branch A, B Power = V1 × Branch Current A/B
Branch C, D Power = V2 x Branch Current C/D
