FAQs

What is the difference between intermittent and continuous rating?

The intermittent rating (1500VA) is the maximum power the transformer can supply for short durations, typically useful for tools with high startup currents. The continuous rating (900VA) is the maximum power it can supply steadily over extended periods.

Can I run two tools simultaneously?

Yes, you can run two tools simultaneously as long as their combined power draw does not exceed the 900VA continuous rating. For tools with high startup requirements, adhere strictly to the intermittent duty cycle.

What does IP44 mean?

IP44 signifies that the transformer is protected against solid objects over 1mm in size (like wires or large screws) and against water splashing from any direction.

Is this transformer suitable for sensitive electronics?

This transformer is designed for construction tools and general site use. For highly sensitive electronics, a more specialized voltage stabilizer or isolation transformer might be required.

How do I reset the overload protection?

Locate the reset button on the transformer unit and press it firmly. If it trips again immediately, there is likely an issue with the connected appliance or a short circuit.

What type of cable is used?

It features a 2m rubber-sheathed H07RN-F cable with a 1.5mm² 3-core conductor, known for its durability and suitability for harsh environments.

What is the purpose of the centre-tapped to earth feature?

This feature enhances safety by ensuring that the voltage to earth is limited, providing an extra layer of protection against electric shock, especially in damp conditions.

Troubleshooting

Transformer not supplying power

Check that the 110V plug is securely connected to the power source. Verify that the tool or appliance is functioning correctly. Press the reset button on the overload protection.

Intermittent power or tool cutting out

The transformer may be exceeding its continuous rating. Disconnect one appliance or ensure tools are used within the specified duty cycle (5min on / 15min off for high loads).

Overload protection constantly tripping

This indicates a fault with the connected tool or appliance drawing too much current, or a short circuit. Disconnect all tools and reset the protection. Test each tool individually.

Visible damage to the casing or cable

Immediately disconnect the transformer from the power source and do not use it. Contact the supplier for repair or replacement.

Pros and Cons

Pros

  • Robust and durable construction suitable for harsh site conditions.
  • Provides essential safety features like overload protection and centre-tapped earthing.
  • Versatile for powering a range of construction tools and lighting.
  • High intermittent rating suitable for tools with significant startup loads.
  • IP44 rating offers good protection against dust and water splashes.

Cons

  • Intermittent duty cycle (5min on / 15min off) limits continuous high-power usage.
  • Requires a 110V plug, necessitating compatibility with site power.
  • Weight of 11kg may make it less portable for some users.

Setup, Compatibility & Care Instructions

Setup:

  1. Ensure the transformer is placed on a stable, dry surface away from direct water ingress.
  2. Connect the integrated 110V 13A plug to a suitable 110V power source.
  3. Connect your 110V tools or lighting to the two 16A outlets.

Compatibility:

  • Designed for 110V tools and appliances requiring up to 900VA continuous or 1500VA intermittent power.
  • Suitable for tools such as hammer drills, impact drills, percussion drills, rotary hammer drills, and industrial appliances like fume extractors.
  • Also recommended for lighting applications on construction sites.

Care:

  • Regularly inspect the GRP case, cables, and outlets for any signs of damage.
  • Keep the transformer clean by wiping with a damp (not wet) cloth. Ensure it is unplugged before cleaning.
  • Store in a dry environment when not in use.
  • Ensure ventilation around the transformer is not obstructed to prevent overheating.
