Ammeter/Voltmeter US301AV

The devices of series US301, namely type US301A (ammeter) and US301V (voltmeter) are designed to measure and monitor the value of current or voltage in AC networks, with a frequency of 50 Hz by voltages or current transformers with output from 0 to 5 mA, 0 to 5 A, 0 to 100 V or directly up to 500 V. There is a possibility the meter to measure an input from 0 to 5 mA constant current.

Microprocessor technology provides reliability, flexibility and economy, while offering the user a variety of options, including an RS485 communication interface. The front panel of the device has a 4-digit red digital display with a height of 9 mm, four LEDs and four buttons.

The digital display shows the measured value and the values of various device configuration parameters. These parameters are selected and adjusted via the front panel buttons according to the specific application.

The measured voltage or current is monitored by two independent alarm levels, A and B, with LED indicators for minimum and maximum value.

The device is supplied in an enclosure with dimensions: front panel 96 x 24 mm, depth 120 mm, for panel mounting.
