RS PRO Chassis Mount, Clamp Construction 230 V ac, 6 VA to 50 VA Mains Transformer

It has been over 100 years since the introduction of the first commercial Transformer when the mass production began. Since then, many additional modifications were developed to support various applications, such as electromagnetic, relays, pumps or heating elements.

The general concept of Chassis Mounting Transformers is around the usage of magnetic induction between coils to convert current and or voltage levels without changing the frequency.

Today, we are proudly introducing our own branded RS PRO Mains Transformer, packed in a chassis mount configuration. Our chassis type Mount Transformer provides a primary voltage rating of 230 V ac and power rating of 12 VA for exceptional isolating qualities. The two separate secondary windings can be connected either in series or parallel to give a wide range of output voltage and current options.

Features and Benefits

The construction of our primary Mains provides double section bobbin fully shrouded

Our Chassis has a full varnish impregnation

Two hole fixing wrap-over clamps

The Transformer has a solder tag termination

100% electrical and flash tested following BS3535 and EN 60742 regulations

Optional terminal shrouds (example 503-912)

The magnetic field that links both primary and secondary windings

Technical product specifications visible on permanent label

Applications

Chassis type has a variety of applications where the Mains Transformer is used, particularly in:

Electromagnetic applications

Electronic and electrical control systems

relays

Pumps

Speed changers

heating elements.
