Programmable Ammeter / Voltmeter
Front size: 48x48mm, 72x72mm, 80x80mm, 96x48mm, 96x96mm, 120x120mm
1. General
The PZ series programmable ammeters and
voltmeters are a kind of programmable electric digital
meters. It can measure electrical network currents or
voltages accurately. With 4 keys on the front panel, we can
set the parameters according to measurement need, such
as ratio CT/ VT, address and baud of communication etc..
They comply EN 61326:2006 and EN 61010-1:2001.
At the same time they can transmit the measure data with
the options of analog output and communication RS485.
With digital input or digital output, they can realize alarming
or controlling the status of switches.
