Hoyt Electrical Instrument Works, Inc. 1.5" Analog VU Panel Meter Presentor AL19 Series

Hoyt is an authorized distributor for the Sifam VU Series in the United States. The Presentor AL19 Series is a 1.5" meter than can be surface mounted (AL19M and AL19B) or window mounted (AL19W and AL19WF). It is constructed with a transparent acrylic front, high impact translucent rear body, and black ABS molded enclosure. The taut band center magnet movement is standard and there is no calibration effect when mounted on a ferrous panel. The combination of tube pointer and flattened arc scale on the buff colored dial results in an easy to read meter, even when monitoring a row on a large console. The performance of the meter is based on the requirements of IEC 268-17. Key Base Specifications and Features (Consult Datasheet or Factory for Complete Details) Accuracy: A low range ac voltmeter offering a performance close to that of a full specification vu meter. Suitable for connecting across a 600 ohm line and self-contained except for requiring an external 3k6 resistor. Calibrated for use with a 3k6 ohm resistor 4vu above the scale marking so that the reference deflection (0vu) is produced by a signal 4vu above 1mW in 600ohms (1.228V). The response curves below give a comparison of the full specification vu meter with that of typical AL19, AL29 and AL39 meters. A variation in over swing between 0 and 5% can occur since the damping is not individually adjusted on each AL meter but allowed to fall within normal process parameters. Operating Temperature: -13°F to 131°F (-25°C to 55°C) Performance: IEC 268-17
