PREMO has extended filters in four wire (3 phase + N) technology for higher power application. FVNSB filters range is now rated from 8 to 600A at 50°C and offer 3-ph+N sum filtering for potentially noisy machines connected to low-voltage electricity networks. The FVNSB series is standard solution for machine tools with up to 12…
PREMO introduces new MV Inductive Coupler Kit
The kit includes two units of its innovative medium-voltage, non-intrusive inductive coupler for smart grids (Prime & G3 PLC) – MICU 300A-S/LF Series. The MICU 300A-S/LF inductive coupler transmits the PLC signals between power lines and the PLC data transceiver without connection of communication cables to power lines. This inductive coupler has a safer installation (High insulation > 5 kV) than a capacitive coupler. Key advantages:…
Filters provide “cleaner” ac power from UPS
An uninterruptable power supply or UPS may be a best way to provide stable power to a company network. Current UPS designs store energy in batteries in dc mode. When necessary, the device supplies power in ac mode, thanks to a dc-to-ac converter. It works in switch-mode and so generates electromagnetic noise, conducted and…
Hall Effect sensors with input reference pin
A series of Hall effect sensors called DSR5 are for a single supply voltage of +5V. The DSR5 series is a close-loop component in a small package for THT mounting. It’s primary winding is integrated, which lets it measure dc, ac and pulse currents on printed circuit boards. Key characteristic include an external pin that…
Hall effect series with 4 to 20mA output
The continuous shortage of Hall Effect sensors is generating trouble for manufacturers such as those for PV and eolic inverters. So, Premo has introduced a family of Hall effect sensors which are equivalent to the LEM DHR-C420 family. The main characteristic of this series is the output current, which has a fixed range of 4…
