LS-series Switchboard Meters

Hoyt Electrical Instrument Works announced the immediate availability of a LS-series switchboard meters. The LS-Series provides high visibility instrument reading for all AC parameters. The scale of each instrument in the series features high visibility markings and a 250-degree full scale deflection. The 4-inch diameter meters are available in a variety of measuring ranges covering DC Amperes and Voltage, AC Amperes and Voltage, AC Frequency, VAR, and Phase Angle. The LS-Series switchboard instruments provide accuracy in accordance with ANSI Class 1.5 for Amperes, Voltage, Kilowatts, and Hertz, and to for phase angle. The instruments use either a moving coil construction for DC measurements, or moving iron construction for AC measurements. The Hoyt LS-Series will support phase angle measurements to 500V at 1A or 5A without the need for an external potential transformer; frequency up to 500V at 1A or 5A without the need for an external potential transformer; AC current up to 5A with out the need for an external current transformer; DC current up to 20A without the need for an external shunt. The Hoyt LS-Series are packaged in a black plastic meter body, with an acrylic resin cover, and Bakelite terminal plate. Mounting is via four studs, with a 4.37” (111mm) panel cutout. Black pointers are provided in all LS-Series models.
