Nortelco Electronics har fått ny webside og webshop
Nortelco Electronics AS ble Adeptor AS fra 1. januar 2022, men dine kontaktpersoner er de samme! Endringen gjelder områdene Elektronikk og Automasjon, og vi har fått ny webside:
Chroma 66203/66204 Power Meters are designed for multiple phase power measurement applications. The wiring mode function allows the user to take accurate power measurements for various wiring modes 1P2W/1P3W/3P3W/3P4W as well as providing accurate standard power measurements common for most electrical devices. A unique feature of the 66203/66204 is its stateof- the-art DSP digitizing technology instead of less accurate and slower traditional analog circuits. The internal 16 bits analog/digital converters with sampling rates of up to 250kHz provide both high speed and high accuracy measurements which is unprecedented within the industry for this class of power meters.
The instruments include a four part display with 7-segment LED front panel readouts. Users can easily select desired parameters and readouts with a touch of a button. The 66203/66204 meters also include remote control using USB or GPIB interfaces via rear panel connections.
The 66203/66204 are packaged in a 3U high, half rack enclosure suitable for bench top or system integration. The power meters are capable of supporting external shunts and CT for higher current application. The 4 channel 66204 is suitable for input and output parameter measurement and efficiency of 3 phase PV inverters can be calculated with measurement of the DC voltage/current at the input side of the inverter.
The 66203/66204 power meters include a 2-shunt design to provide high accurate readings for both low and high current measurements. The power meters also suppor t features such as Inrush current, Total Harmonic Distortion of V/I, and Energy measurements. With these practical functions, the 66203/66204 power meters are suitable for meeting the demanding tasks of R&D, production and quality control departments.
