Designed specifically for power measurements on single-phase AC power supplies, Saelig has introduced the GW Instek GPM-8213 AC Power Meter. This instrument offers high-accuracy voltage, current, and power measurement capabilities from both front- and rear-panel inputs, presenting users with clear, convenient, and accurate AC power measurements. The GPM-8213 provides two display modes in order to maximise its measurement usefulness.
In the Standard Mode it simultaneously displays eight measurement parameters (two major measurements and six secondary measurements and related measurement settings); this is suitable for R&D and engineering situations. The Simple Mode displays only four measurement parameters, which is more suitable for production environments.
The 19 power measurement parameters include: voltage (Vrms/V+pk /V-pk), current (Irms/ I+pk /I-pk), frequency (VHz/IHz), power (P/ P+pk /P-pk), crest factor (CFV/CFI), apparent power (VA), reactive power (VAR), power factor (PF), phase angle (DEG), total harmonic distortion (THDV/THDI), and high-accuracy voltage/current/power measurement capabilities (reading: ±0.1%; level: ±0.1%).
Compared with products of the same category, the GPM-8213 provides more diverse measurement parameters and functions. The GPM-8213 also features an Integral Measurement function for indicating a test device’s power or current consumption over time. Users can set a measurement period to show transient power integration, dividing the result by elapsed time to calculate the test device’s average power.
The GPM-8213 can fully meet the requirements of IEC 62301/EN 50564 standby power consumption testing, with a measurement frequency bandwidth of DC to 6kHz, minimum current level of 5mA (resolution: 0.1µA), and power (1µW for minimum current and voltage levels, 1mW for maximum current and voltage levels). For larger power measurements users can utilise the terminals on the rear panel to conduct 600V/20A measurements using an external transformer: set the multiplying factor (1-9,999) to modify the displayed readings of the input voltage or current values without additional calculations. The built-in RS-232C, USB, and LAN interfaces can be used for external control and automatic test system requirements.
Made by the Taiwanese test and measurement specialists GW Instek, the GPM-8213 AC Power Meter is available now from Saelig.
