The Power in Electrical Safety® PEM353 Universal measuring device

Universal measuring device Product description The digital universal measuring device PEM353 is used to record and display measured quantities of an electricity supply network, and make them available via the communication interface. The range of measurements extends from voltages and currents to power and energy meters to measured quantities of the voltage quality, such as THD and the individual harmonics up to the 31st order. The PEM353 is suitable for use in 2-, 3- and 4-wire systems and in their respective versions as TN, TT and IT systems. This allows monitoring single and polyphase systems....

Universal measuring device PEM353 1. Measurement of electrical quantities such as - Phase voltages (individually + I) - Line-to-line voltages (individually + I) - Phase currents (individually + I) - Neutral current In (calculated) - Residual current Ir (calculated, PEM353-N only) in A - Power per phase conductor (individually + I) - Displacement factor (individually + I) cos (9) - Power factor (individually + I) A - Active and reactive energy import (individually + I) in kWh, kvarh - Active and reactive energy export (individually + I) in kWh, kvarh - Voltage phase angle (LN or LL, individually)...

Universal measuring device PEM353 Z BENDER Indication of energy pulsing Indication of communication activity The function of the buttons varies depending on the context. The meaning is always shown on the display above the corresponding button. 1 - Measuring voltage inputs: The measuring leads should be protected with appropriate fuses. 2 - Supply voltage: Power protection by a 6 A fuse, quick response. If being supplied from an IT system, both lines have to be protected by a fuse. 3 - Measuring current inputs I4 (only PEM353-N) 6 - Digital outputs (N/O contacts) 7 - Measuring current inputs...
