Amorphous Core Transformer

Amorphous Core Transformers

These Isolation / Ultra Isolation Transformer use an amorphous alloy in their iron core which improves electrical characteristics and significantly reduces energy loss.


What is an amorphous core Isolation transformer?


The role of an Isolation transformer is to protect Electronic & Sophisticated equipments, CNC Machines from the excessive line voltage transients, spikes / surges produced in the system. Electrostatic shielding helps in grounding these spikes & not allowing to pass on to the secondary side of the transformer. Any transformer operate 24 hours a day, seven days a week during which time they undergo constant losses of 2 to 4% of the electricity that passes through them. This loss is divided into two different categories: load losses caused by the load on the transformer during the use of electricity and no-load losses (standby electricity) caused regardless of whether a load is present. Amorphous core transformers significantly reduce no-load losses by using an amorphous alloy for the iron core, which the transformer windings that carry the electricity are coiled.


Specification:

SERVOMAX make 3-Ø Amorphous Core Isolation Transformers 50 Hz or 1 KHz with primary Voltage 360-480V & Secondary voltage 380-415 Volts, 120/240 Volts or as required, Oil immersed, naturally air cooled, double wound with Aluminium / Copper, Step up / Step down core type continuous duty transformers having no load voltage ratio from 200 VA to 160 KVA with ‘H’ Class Insulation and designed to withstand Short Circuit, & Impulse Test in accordance with IS 2026.

Efficient and environment friendly:

The Ultra-low core losses (No-load) of an amorphous core isolation transformer yields substantial energy and cost savings for its owner. In fact, amorphous core transformers can lower core loss by 60-70 percent compared to transformers made with conventional cold-rolled grain-oriented (CRGO) cores, resulting in cost avoidance from reduced generation and deferral of generation and transmission capacity expansions.

The reduced core loss of an “ACIT” lessens impact on the environment by reducing carbon emissions over the transformer’s entire operating life. Also, the amorphous metal core manufacturing process is more efficient, using less energy than required to manufacture CRGO cores. And, amorphous metal cores, along with the copper, aluminum, and oil components can be recycled, promoting conservation of these valuable resources.

Applications:

For a wide range of high frequencies and hot-spot temperature (up to Class H), C-Cores & E-Cores are used in a growing list of advanced power conditioning applications including:

  • Switch Mode Power Supply.
  • UPS Harmonic Filter Inductors.
  • Uninterruptible power systems.
  • Welding power supply.
  • Power inverter (e.g. solar inverter).
  • Wind generators.
  • Automobiles.
  • Railway Traction.
  • High-Power Industrial Ballasts.

Advantages:

  • High Saturation Flux Density (1.56 T).
  • Low Profile - enables weight and volume reductions of up to 50%.
  • Low Temperature Rise - enabling smaller compact designs.
  • Low loss - resulting from extremely thin Iron Based Amorphous ribbon (25 um).
