Overview
The UL listed Whirlwind PL-PM1RJ Power Meter is designed for monitoring voltage, current and frequency on 3 phase Y power with three 120 Volt AC legs or single phase AC with two 120 Volt legs. The PL-PM1RJ monitors line to neutral and line to line voltages and line current values. Additionally, neutral to ground voltage and line frequency are monitored. A new enhancement of the PL-PM1RJ now allows network connectivity for remotely viewing power distribution parameters in real time. IP based design permits Internet accessibility. The Whirlwind PL-PM1RJ Power Meter can be used with portable AC distribution and permanent power distribution systems. The PL-PM1RJ can be included in Whirlwind Power Link distro systems and also can be purchased separately for any applicable use. The Pl-PM1RJ is also available with a current sensing transformer kit.
Display Mode Description:
- Apply Power.
- The power on sequence will illuminate all LEDs on the front panel.
- The Software Revision is then displayed in the lower right hand display.
- Mode A Voltage (blue LED) and current measurements will display.
Mode A Voltage Display (blue LED reference)
The TOP row of displays will show (left to right):
- X Leg to Neutral voltage
- Y Leg to Neutral voltage
- Z Leg to Neutral voltage
- Safety Ground to Neutral voltage
Mode B Voltage Display (red LED reference)
The TOP row of displays will show (left to right):
- X-Leg to Y-Leg voltage
- Y-leg to Z-Leg voltage
- Z-Leg to X-Leg voltage
- Frequency
Amperage Display (mode A and B)
The bottom row of displays will always show:
- X-Leg current
- Y-Leg current
- Z-Leg current
- Neutral Leg current.
Flashing Display Notifications
The Voltage displays will flash when a voltage is out of range.
- In Mode A, the X, Y, or Z to Neutral voltage display will flash when the voltage is below 108 Volts or above 131 Volts.
- In Mode B, a voltage display will flash when the voltage is less than 187 Volts or grater than 228 Volts.
