Digital Meters: Amp, Volt, VAF, Energy & Multifunction

Digital meter price list (incl. GST): Selec digital ampere meters from ₹526, digital volt meters from ₹550, three-phase volt amp (VAF) meters from ₹1,181, energy meters from ₹1,946 and multifunction meters from ₹2,642 (volt, amp and watt in one meter). Sizes 96×96, 72×72, 48×96 mm and DIN rail.

A digital ammeter (digital AC ammeter or panel amp meter) shows the current on one line, a digital voltmeter shows the voltage, and a volt amp meter shows both, plus frequency on VAF models. Energy and multifunction meters add kW, power factor and kWh.

Types of digital meter

Digital meter price list: amp, volt, VAF, energy and multifunction

Wiring guides: digital ammeter, volt amp (VAF) meter, Selec MFM383A wiring and settings, and the digital panel meter buying guide.

Sizes and panel cut-outs: 96x96, 72x72, 48x96

The same reading is available in several front sizes, so match the cut-out already in your panel door. For example, the Selec MA302 (96x96), MA202 (72x72) and MA12 (48x96) ammeters all cost ₹526. Every product page links to the Selec datasheet.

Do I need a CT with a digital ammeter?

Yes, for currents above 5 A. Selec MA-series ammeters are CT-operated with a 5 A secondary, and the CT primary is programmable from 5 to 4000 A, so one meter model fits most feeders. VAF and multifunction meters also read current through CTs. For CTs or help choosing a ratio, WhatsApp us. See how to choose and connect a digital ammeter and the volt-amp-frequency (VAF) meter guide.

How to choose a digital meter

• What to read: current, voltage, frequency, power or energy (see the tables above).
• Range: above 5 A you need a CT with a 5 A secondary; set the CT ratio in the meter.
• Front size: 96×96, 72×72 or 48×96 mm to match the panel cut-out, or DIN rail for energy meters.
• Communication: choose a -C model for RS485 Modbus to a PLC or SCADA.

Frequently asked questions

What is a digital meter?

A digital meter shows an electrical value (current, voltage, frequency, power or energy) as numbers on an LED or LCD display. In control panels these are called digital panel meters and fit standard door cut-outs such as 96×96 mm.

What is the price of a digital amp meter in India?

On Voltkart, Selec digital ampere meters (MA12 48×96, MA202 72×72, MA302 96×96) cost ₹526 each including GST. Digital volt meters (MV15, MV205, MV305) cost ₹550, and volt-amp-frequency (VAF) meters start at ₹1,181.

What is the price of a digital meter?

Single-reading digital meters start at ₹526 (Selec ammeter or voltmeter), VAF meters at ₹1,181, energy meters at ₹1,946 and multifunction meters at ₹2,642, all including GST.

Which is better: a separate amp meter and volt meter, or a volt amp meter?

For a single motor or feeder, one ammeter plus one voltmeter is the lowest cost. For a three-phase panel, a VAF (volt amp frequency) meter shows all three readings on one 96×96 display, saving door space and wiring, and it can scroll through the phases.

Does a digital ammeter need a CT?

Yes, for currents above 5 A. Selec MA-series ammeters are CT-operated with a 5 A secondary, and the CT primary is programmable from 5 to 4000 A, so one meter model fits most feeders.

How do I connect a digital volt amp meter on a 3-phase supply?

Connect the voltage inputs to R, Y, B and neutral through a small MCB or fuse, and pass each phase through a CT whose 5 A secondary goes to the meter current terminals. Set the CT ratio in the meter menu. The wiring diagram is on the meter label and in the datasheet linked on each product page.

Which size should I buy: 96×96, 72×72 or 48×96?

Match the cut-out already in your panel door. 96×96 mm is the most common size on LT and MCC panels, 72×72 suits smaller doors, and 48×96 fits where width is tight. The readings are the same across sizes.

Is a digital panel meter the same as an electricity board meter?

No. Electricity board (utility) meters are supplied by your DISCOM. The meters here are for panels and sub-metering: Selec EM2M and EM4M DIN-rail energy meters measure kWh for a tenant, machine or floor, and EM306 does the same through CTs.

Digital or analog panel meter?

Digital meters are easier to read, more accurate and can be programmed for any CT ratio, so one model covers many ratings. Multifunction meters can also send readings to a PLC or SCADA over RS485.

Are these meters genuine, with a GST invoice?

Yes. Voltkart is an authorised distributor of Selec and Cautoni Swastik, and every order ships with a GST invoice and pan-India delivery.
