Description
Trumeter Power Signal Conditioner for Single, Split & Three-Phase Monitoring
The Trumeter Power Signal Conditioner (SC-PWR-DIN) is a DIN rail-mount device that measures power, voltage, current, frequency, power factor, and THD across single-phase, split-phase, and three-phase networks (1P2W, 1P3W, 3P3W, 3P4W). As a result, one unit covers switchboard monitoring jobs that would otherwise need separate meters for each network type.
- Measures power, voltage, current, frequency, power factor, and THD
- Configurable CT and PT ratios for a wide range of installations
- Modbus RTU over RS485 for SCADA and BMS integration
- 2 opto-isolated digital outputs plus a 4-20mA analog output
- 10 independent alarm setpoints with programmable delays
Because CT and PT ratios are configurable in software, the same unit can be applied to a small distribution board or a large three-phase switchboard without ordering a different model. For example, use it to trend energy use on a factory main incomer, then redeploy a spare unit on a sub-board. Modbus RTU output means it also drops straight into an existing BMS or SCADA network via the APM Gateway and Trumeter Cloud.
Configuration and Installation
The unit clips onto standard Top Hat Slotted (TS35) DIN rail and measures 72mm x 72mm x 80.6mm, a little deeper than the single-input signal conditioners to accommodate the extra measurement circuitry. It runs from a 100-277V AC supply at a maximum 2W consumption, so it can be powered from the same board it is monitoring. Therefore, no separate low-voltage supply is needed for most switchboard installations.
The unit carries CE, cUL, UL, RoHS, and IP20 ratings, covering most industrial and OEM panel-building requirements without extra certification paperwork.
