Power Source For Teacher Manufacturer,Supplier and Exporter in India

Power Source For Teacher (Product Code: SCL1427/012) is a demonstration-table power unit with two separate outputs: an alternating (AC) source on one pair of terminals and a continuous (DC) source on the other pair. The output is adjustable from 2 to 24 V (minimum range) on a graduated control, supplies a maximum current of 5 A, and is protected against short circuits, while a built-in voltmeter and ammeter let the whole class see the voltage and current. Made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a practical power supply unit for lab demonstrations in India.

Specifications

Typical Use

From the front bench, a teacher can run the DC terminals into an electrolysis cell, an electromagnet or a resistance wire to show chemical, magnetic and heating effects of current, then switch to the AC terminals for a demonstration transformer or induction experiment. Because the meters are built in, students read the voltage and current straight from the unit while the teacher varies the setting, which makes Ohm's law and power calculations easy to follow in real time.

Good practice is to turn the control to its lowest setting before switching on, make all connections with the unit off, and raise the voltage gradually while watching the ammeter. If the short-circuit protection operates, switch off and check the wiring before trying again. Always plug into an earthed 220 V socket so the earth conductor can do its job.

Manufacturer

The unit is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and produces electrical demonstration apparatus for school and college physics. Further information is available on the ScienceLab company profile.

Frequently Asked Questions

Does it provide both AC and DC?
Yes. Two terminals give an alternating (AC) output and the other two give a continuous (DC) output.

What voltage and current can it deliver?
The output is adjustable from 2 to 24 V (minimum range) on a graduated control, with a maximum current of 5 A.

What happens if the output is short-circuited?
The unit has short-circuit protection. Switch it off, find and correct the fault in the circuit, then switch on again at a low setting.

What mains supply does it need?
It is specified for a 220 V supply through a plug with an earth conductor. If your country uses a different mains voltage, tell us before ordering so we can confirm suitability.

Is it intended for student benches?
It is designed as the teacher's source for demonstrations. If you also need supplies for student groups, mention the number of benches in your enquiry.

Can a calibration certificate be provided for the meters?
Please discuss calibration-certificate needs with us through the contact page before placing an order.

What warranty applies?
Warranty terms are stated in our written quotation; ask for them when you request a price.
