The digital power meter GOBLIN is a micro-controller based unit which not only measures a host of electrical parameters to display them on a 128 x 64 backlit LCD, but also acts as a comprehensive load managing device due to its four numbers of output relay contacts. These outputs are individually field programmable for both the parameter on which to generate alarm as well as the values on which to activate alarm and deactivate it. In addition to this flexibility in terms of load management, the meter also has two serial ports: USB port and RS485. RS485 supports MODBUS RTU protocol for connections to EMS/SCADA. Goblin has two USB ports-one where a cable connection to laptop/pc is made(Device mode) and another where the unit directly accepts a pendrive(Host mode).
The unit is meant for use in three phase four wire / three wire systems. The installation type, CT ratios and PT ratios are site selectable.
The Load Manager with its four relay contacts can be used as a Demand Controller. The method of Demand calculation is sliding window and fixed window.

EMPOWER from Trinity is an electrical power meter, for use in three phase three/four wire electrical systems. It measures the phase voltages, currents, PF, Hz, system KVA, system KW, system KVAr, Active Energy (KWh) and Apparent Energy (KVAh). The various parameters measured are displayed on a 4 digit x 3 Row Red 7 segment LED matrix for easy visibility and readability. The CT ratio (primary) can be programmed at site using the front membrane key. The meter uses state of the art Digital Signal Processing (DSP) circuitry to achieve very high accuracy measurement of true RMS value of all above parameters. The meter accuracy is class 1.0 for all parameters including KWh.
The VAF model meters from Trinity are True RMS type digital meters for use in three phase four wire LT electrical systems. The design of these meters is based on proven micro-controller technology, resulting in compact and accurate meters. The design uses powerful micro-controller based technology. The meter uses state of the art Digital Signal Processing (DSP) circuitry to achieve very high accuracy measurement of True RMS value of all parameters. The meter displays the readings on Crisp Super bright LED Displays.
