Howard Butler Ltd

Howard Butler Ltd has been manufacturing panel meters, current transformers, relays, transducers and associated products in our UK factory for over 85 years.

Howard Butler Ltd has ISO 9001:2008 approval with a constantly reviewed quality policy. This ensures that through our  vigilance, control, design methods and accountability throughout all stages of design and manufacture quality is designed and built into our products. Our in-house design engineers are able to work with customers to provide custom solutions where our standard product range is not applicable. Our policy is one of continuous improvement, therefore the HOBUT range is regularly added to with new products, mostly designed to IEC, BS, or DIN specifications.

 

We hold extensive stocks of vital components to ensure quick delivery of both standard and special
products. Customer satisfaction is central to the aims of Howard Butler Ltd, with our fully integrated
computer system closely controlling orders, enquiries and stock.

  1. Phase Angle Transducer

    Phase Angle Transducer
    • Part codePhase Angle Transducer
    • ManufacturerHOBUT
    • Price£POA
    The M100-PA series of phase angle transducers measure the phase angle between current and voltage. They can be used on single and three phase 3 or 4 wire balanced systems. Ideal for optimising power factor correction. The MP100-PV1 measures the phase angle between two voltage supplies and provides a D.C. output signal proportional to the phase angle between the voltages.

  7. Reactive Power Transducers

    Reactive Power Transducers
    • Part codeReactive Power Transducers
    • ManufacturerHOBUT
    • Price£POA
    The M100-XA series measure reactive power in single, 3 phase 3 or 4 wire balanced and unbalanced systems. Using the time division multiplier circuit means that they can be used over a wide range of input waveforms. The D.C. output signal is directly proportional to the instantaneous reactive power being measured. Typical Applications include the measurement of reactive power in switchboards, power stations and generating sets etc. The high isolation of 4kV as with all M100 series allows these transducers to be connected to a variety of measuring and control devices and systems, such as analogue meters, PLC, computer systems, data loggers, digital instruments and telemetry systems. Both auxiliary powered and self powered versions of each type are available. It is recommended to use an auxiliary powered version if the system being measured has voltage variations in excess of ±20%
