Description
Multi Tap Transformers allow greater flexibility in managing multiple wire runs by moving cables up and down the multi range. Our Resin Sealed Transformers ensure highest possible efficiency & reliability.
Features
Low Voltage Transformer ranging from 75 W - 1200W 120, 277 /12, 13, 14, 15V with Toroidal /EI.
50/60 Hz
Protection for each output circuit.
Photo cell Option
Rainproof Enclosure
Stainless Steel / Powder Coated.
The Transformer used in the power supply unit is manufactured as per the UL norms.
The transformer will be potted/sealed in an enclosure using Epoxy (a mixture of Resin Hardener) which ensures high reliability and efficiency.
The enclosure is made up of Prime Stainless Steel material SS 304 grade (also carbon steel with powder coated enclosure can be provided on request )
Block Terminals will provide the easiest way for the customer to connect the secondary tappings. Photocell and timer connected as per the customer's needs.
A circuit breaker of 25A is provided for circuit protection.

Standards
The product performance is in accordance with GB20840.1 GB20840.2 and IEC61869-1 IEC61869-2 standards.
Transformer Standard current transformer are also called precision current transformers, current transformer standards, standard CT and current transformer standards. Transformer standards are divided into current transformer standards and voltage transformer standards. Standard current transformers are used in the error test of transformers. Used as a current transformer calibration standard
technical parameter
1. Temperature:
2. Relative humidity
3. Rated Primary Current:5-5000A 5A,1A
4.Rated secondary current:5 1A
5 Accuracy Class 0.05S
6. Allow long-term work under the rated current; More than120A across the core.
Precautions:
1. The current of standard CT and tested CT must be the same in CT calibration.
2. Follow the given wiring diagram strictly.
3. Test whether the load box is accurate or not before calibrating the transformer.
4. Forbid secondary winding opening during the calibration.
5. Select demagnetization before calibration.The wiring diagram is shown in figure 5.
Short out the secondary winding before cutting off the power when the demagnetization is finished.
6.Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.
