Chapter 2 Installation DC Measurement
PM130 PLUS Powermeter Series_Installation Operation and Manual 36
2.5.2 DC Current measurement (Hall Effect Sensors)
The device has 3 independent currents rated at 20mA nominal current to which the user may connect
standard Hall Effect sensors featuring 0-20mA/+-20mA outputs.
DC power is calculated with indication for direction of power flow.
Energy for each channel is calculated separately.
Typical Current measurement accuracy: better that 0.5% (depending on HES type)
It is recommended to use Satec HEPS +-15VDC independent power supplies as the HACS
Notes:
• It is mandatory to use cabling featuring double insulation (600V) when connecting HE sensors to
the meter
• It is mandatory to use a separate power supply for each sensor.
Requirements for power supply for Hall Effect Sensors:
• Double insulation
• No Ground connection permitted
• Overvoltage withstand of 3kV or more
• Satec HEPS (Hall effect sensor power supply) or: 15V DC or +/- 15VDC (or 12VDC) power supply,
depending on HSE type
• UL Listed
DC power is calculated with indication for power flow direction.
