Power Supplies & Chargers

Keeping your electrotherapy equipment powered and ready

A power supply or charger might be the smallest part in the box, but it's usually the first thing to fail. A worn adaptor or a dead charger takes a perfectly good ultrasound, laser, or muscle stim unit out of action just as fast as a broken probe. This range covers replacement mains adaptors, dedicated chargers and power units for the electrotherapy and physiotherapy devices used across UK clinics, from single-practitioner rooms to NHS Trust departments.

Finding the right charger for your device

Most of the units listed here are matched to a specific make and model, from the Trimwave charger and VET H-Wave chargers through to Biomag, EMS Primo, Enraf Nonius Sonopuls, Gallium laser and Photizo chargers. In case you are uncertain about what kind of power adapter is needed for the device, please check the SKU or the model number of the unit at the bottom of it and compare with the name of the product. Plugging an incorrect charger into the device is not only impractical but may lead to irreparable harm to the battery or the device.

Trimwave charger and H Wave power supplies

The trimwave charger is one of the more frequently reordered items in this category, alongside the VET H-Wave Version 1 and Version 2 chargers used with h wave devices in equine and small animal therapy settings. If your H Wave  won't hold charge at all, a replacement charger is usually the first and cheapest thing to try before assuming the device itself needs a repair.

When to replace vs when to get it looked at

If a device won't power on at all, a faulty charger or power supply is one of the more common and least expensive causes, well worth ruling out before booking equipment in for a service. If a new charger doesn't resolve the issue, our engineers can assess the unit itself as part of our equipment servicing and repair service.

Charger vs Power Supply

The function of a charger is to recharge the internal battery of an instrument, whereas the purpose of a power supply is to run the unit via mains power. Some units, such as the Osteotron IV, use an AC adapter (power supply) instead of a battery charger.
