Elster A100C Power Meter

The successful range of A100 meters from Elster Metering Systems provide a cost effective solution for one or two rate domestic applications. The new A100C meter is housed in an extremely compact case. To further enhance security, the main meter cover is permanently secured to the base during the manufacturing process. The meter also provides the choice of IrDA communications or optical IEC 62056-21 (formerly IEC 61107) communications.

The liquid crystal display has large (9.8mm), high contrast characters that can be viewed from a wide angle. Chevrons and multilingual legends on the nameplate identify the values being displayed. The energy registers can be configured for the required number of digits and for the position of the decimal point.

The A100C offers high security and detects many of the most commonly used tamper techniques. Security features of the meter include reverse run energy total and count; power fail and elapsed time count; hours in anti-creep; hours in Rate 1, Rate 2 and hours since last power up time. These are stored as security data and can be included as part of the display sequence and read via the optical communications ports.

The A100C has the option of IrDA or optical IEC 62056-21 (formerly IEC 61107) communications. Both methods of communication allow the meter registers and security data to be read electronically from a laptop or hand-held device, greatly reducing the possibility of manual meter reading errors.

The A100C can be a simple import meter or for import/export for domestic or small scale generation sites. The meter offers one or two rate operation. The rate select for the two rate meter is switch to neutral.

Meters can be supplied to meet accuracy Class 1 or Class 2 requirements. They are approved to EN 62053-21:2003, have an ingress protection of IP53 to IEC 60529:1989 and comply with EMC standard EN 50081-1:1992.
