To measure current on a high-voltage DC bus, put a shunt in the bus and read it with a transducer that sits at bus potential and isolates the signal....Read More

A power meter tells you how much power and energy a circuit used. A power quality analyzer also records how good that power was, event by event. The...Read More

To get 24 V control power from a high-voltage DC bus, use a DC/DC converter rated for the full swing of that bus. To run an AC motor load from the...Read More

To find out which machines drive your plant's demand charge, you need two records. The first is a meter on the service that records demand the way...Read More

To put an RS-232 instrument on a network and keep the software working, use an Ethernet to serial unit. The unit connects to the instrument's serial...Read More

You can get data off a machine without changing the PLC program by reading the signals at the terminals and the serial ports, beside the controller...Read More

NFPA 79 is the Electrical Standard for Industrial Machinery. It picks up where UL 508A stops, at the enclosure wall, and covers the electrical...Read More

Every power drop in a Northern California or Northern Nevada facility ends the same way. A human hand mates the connector. During the build. During...Read More

DC contactor datasheets lead with the cycle count. It is the first number engineers compare, and it carries an implied weight of reliability that it...Read More

Your meter says the contactor is fine. Whether it can still break a 1,500-volt DC arc is a different question and nothing on the outside will tell...Read More
