Panel Mounting Toroidal Transformers

Amalgen Series 202 toroidal transformers offer significant advantages over other construction methods for switchboard use. To the obvious advantages of smallness and lightness can be added the lower external field, low lamination hum and virtual elimination of leakage inductance. The nearly zero leakage inductance is a particular advantage where the voltage drop associated with high inrush currents may lead to impaired performance of the connected equipment. Small footprint size and two hole mounting is a further advantage to panel builders.

 

This range of toroidal transformers is available from 30 VA to 1000 VA. A wide range of voltages are available with only the most common ones shown below. Dual output voltages with a common connection are also available. Please email us for your particular requirement. A terminal rating of 20 A sets a limit on VA rating available for lower voltage transformers.

Panel Mounting Filter/Transformers

Amalgen Model 6771 panel mounting filter/transformers are a combination of a toroidal transformer and a mains filter mounted in a ventilated enclosure for switchboard use. Toroidal transformers offer significant advantages over other construction methods for switchboard use. To the obvious advantages of smallness and lightness can be added the lower external field, low lamination hum and virtual elimination of leakage inductance. The nearly zero leakage inductance is a particular advantage where the voltage drop associated with high inrush currents may lead to impaired performance of the connected equipment.

 

This range of toroidal transformers is available from 160VA to 500VA. A wide range of voltages are available with only the most common ones shown below. Dual output voltages with a common connection are also available. Please email us for your particular requirement. A terminal rating of 20 A sets a limit on VA rating available for lower voltage transformers.
