Carroll & Meynell Portable Safety Isolating Site Transformer 500 VA, 230 V ac Primary, ±55 V ac Secondary, 4 A Output CM10001

Carroll & Meynell CM10001 is a portable safety isolating site transformer designed for robust and safe electrical power distribution on construction sites and industrial settings. It features a 500 VA power rating, with a 230 V ac primary voltage and a ±55 V ac secondary voltage with 4 A output current capacity. The unit is encapsulated in a rugged GRP insulated and splashproof enclosure, ensuring durability and protection in harsh working environments.

The transformer employs double-wound construction which facilitates electrical isolation between the primary and secondary windings, significantly reducing shock hazards. Its secondary winding centre-tap is earthed to further enhance safety. For protection against overload and overheating, a thermal safety fuse is embedded in the primary winding and a resettable thermal cut-out is integrated in the primary circuit.

Designed for convenience, the transformer includes an approximately 2-meter mains cable fitted with a Type G British 3-pin plug, and the socket complies with the BS EN 60309 standard. Its free stand mount type and compact footprint of 170 mm length, 180 mm width, and 180 mm depth make it appropriate for portable use and easy placement within site environments. Weighing 10.5 kg, the unit balances portability with robustness.

The unit operates effectively within a frequency range of 50 Hz to 60 Hz, suitable for typical industrial and construction power supply standards. Features a 500 VA power rating with single-phase input and ±55 V ac secondary output voltage.

Equipped with a 4 A output current and 230 V ac primary voltage. Includes double-wound construction for electrical isolation and safety. Secondary centre-tap is earthed to minimize shock risk. Thermal safety fuse is embedded in the primary winding for overload protection.

Resettable thermal cut-out in primary circuit prevents damage due to overheating. Comes with approximately 2-meter mains cable fitted with UK 13A plug. Designed for free stand mounting with BS EN 60309 socket type compatible with Type G British 3-pin plug.

Compact dimensions: 170mm length, 180mm width and depth, weighing 10.5 kg. Operates reliably within frequency range of 50 to 60 Hz.

This Site Transformer is ideal for industrial, construction, and maintenance use cases where safe isolation and voltage conversion are critical. Its portable and splashproof design makes it suitable for demanding field operations.
