Description Overview The Cashpower Gem Lite is a compact single phase, two wire, 80 Amp, STS keypad prepayment meter in a British Standard (BS) housing. The meter is suitable for new installations or retrofitting of existing bottom connected electromechanical or electronic watt-hour meters. The meter is easy to install and boasts an easy to read, language independent Liquid Crystal Display (LCD) and a wide range of information registers which can be easily accessed by pressing the information button on the keypad and then entering the number of the register. (Refer to the User Guide for more information.) The meter operates on Landis Gyr’s version 12.3 meter firmware, and therefore provides only for STS prepayment functionality mode.

The use of these mechanical seals ensures that there are visible signs of tampering if unauthorised entry to the system is attempted. In addition, the meter is equipped with a tamper sensor that will automatically disconnect the power to the load in the event of tampering. The meter includes a Significant Reverse Energy (SRE) detection feature. If the line and load wires are swapped during installation, the meter will continue to operate and decrement credit, however, the meter can be factory-programmed to tamper and disconnect the load should SRE be detected. Virtual Token Carrier (VTC) port The Gem Lite is fitted with an industry standard VTC port at the rear of the meter. While this port is typically used to program the meter during the manufacturing process, it can also be used to extract vital meter information, such as remaining credit. Surge Immunity The meter exceeds the IEC62055-31 Voltage Impulse Withstand of 4kV.
