Control Transformers

 

Control Trasformers

Screenshot 2020-10-09 124554.png

Control power transformers from NEPEAN Power set the industry standard for design innovation and performance.
They are designed with low impendence windings for excellent voltage regulation, and can accommodate the high inrush current associated with contractors, starters, solenoids and relays.


Transformers provide stepped down voltages to machine tool control devices enabling control circuits to be isolated from all power and lighting circuits. this allows the use of grounded or ungrounded circuits that are independent of the power of lighting grounds; greater safety is afforded to the operator. The control transformer line is particularly adaptable on applications where compact construction is demanded.

Features

• Single and Three Phase Transformers
• VA load for 50 to 100 kVA
• Input voltages 24V - 6600V
• Models available with Integral Fuse Blocks
• Earth Screen shields between windings
• Centre Tapp
• Optional Primary Tapp for regulation
• Class F Insulation (optional)

The NEPEAN Power Constant Voltage Transformer has a wide application, particularly where reliability and inherent regulating ability against line voltage changes are of prime importance. The output of the constant-voltage transformer is essentially a square wave, which is desirable for rectifier output applications while, also having good circuit characteristics.

Features

• Bottom plate is built of powder coated steel. Thickness is 1.5mm.
• Mounting holes are unknown and subject to customer’s confirmation.
• Length and gauge of wires suit the transformer.
• Weight of the whole asm is around 15KGS.
