MBPF-1 is Delta own development, signifying the ultimate in expertise that has been achieved in electrical parameters measurements.

MBPF-1 is one of the most advanced instruments of its kind, employing the latest microprocessor technology. The circuitry is used. An absolute accuracy of 1.0 degree in phase angle measurements assures the computed power factor be accuracy of measurement is independent of line frequency variations.

Introduction of composite V-A-W Meters by "Delta" in 1989 has been a runaway success;their large number in the field all over the Country bears testimony to their performance and reliability. "DELTA" have also been the pioneers of the Digital Wattmeters in the Country since 1982. Those electrical engineering industries which comply with BIS standards, they will find Composite V-A-W meters as a necessity. The concept composite not only dose away with interconnecting wiring, it also saves space in the panel and is economical too.Applications are in: Domestic Appliances Manufacture, such as fans, mixes, hotplates.Lighting Equipment Manufacture.F.P.H. Motor IndustryIndustrial Heater Manufacture.When used PC/ CT signals, composite V-A-W meters are useful for utilies as well.

SPECIFICATIONS:

DIMENSIONS: 290mmW x 180mmDAUX. SUPPLT: 200-250 VAC @ 8 VAFREQ. RESPONSE: 10Hz- 10kHz (all displays)CONNECTIONS: 1) Aux. supply by barrier terminals on the rear2) Load supply/ load terminal of 4 mm - 15A rating on the front dial (rear connections only against specific request.)a) True-RMS version of DT-200 (SP) is DTRMS-200, having the same specifications except the voltage & the current displays are of true- RMS type. All of the Delta's digital wattmeter are of true - RMS type. DTRMS -200 is very useful for measuring distorted current waveforms especially in electronic ballasts.b) When using DT-2000/ DT-2000 (SP), if frequent heavy starting surge currents are encountered, the use of external CT operated models, for more reliable operations, is suggested.c) For custom-built models send with your specific requirements.

PROTECTION:

1) The aux. supply to the instrument is protected by a metal-oxide varistor against high voltage surges. However inductive loads such as a contractor-coil, heavy- duty transformers, etc. should not be connected across the same supply.2) The voltage sensing circuit is protected by a heavy-duty metal-oxide varistor of 500V rating connected across the load terminals. Hence the load supply should not exceed 500 VAC.3) The current sensing circuit is protected by a replaceable glass-cartridge fuse on the rear of the instrument. This glass cartridge fuse should not be replaced by fuse of higher ratings or wire shorts. Otherwise the instrument may get damaged.

MFC - 4 is a new generation of digital panel meters, utilizing the latest microcontroller technology. It computers frequency by very precise cycle width time measurements, also it has an elaborate noise discrimination algorithm.

The instrument can be connected by an optional RS-485 (MODBUS - RTU) output. Thus it can be used as a component of a data system.

MFC- 4 is precision instrument finding applications in Power Houses, Labs, Test Benches etc. The Instrument uses very high professional grade components offering unsurpassed reliability.

Over the last 32 years, Delta have supplied virtually thousands of custom-built-equipment. Various industries spanning from caustic soda plants, aluminum plants to electrical equipment mfrs. like switchgear, motor/pumps appliances etc. For switchgear division of L & T, we have fabricated a range of equipment to suit their testing needs. Tailor made DPM's such are these with isolated 0 -10 VAC interface outputs or with band-pass comparator set-point limits have satisfied many different testing needs.
Delta's specialty has been the value addition to their standard range of equipment for creation of specific application equipment.
