Frequently Asked Questions
- Will PowerGuard products protect my equipment from a lightning strike?

- What are the differences between the PowerGuard (PG3701) and the Power Filters (CPF3500, CMP3901, and CMP3903)?

- Why do I need to use a PowerGuard when I have a Filter?

- I understand the basics but how does the PowerGuard Protect?

- How does the Professional Series Filter Protect?

- What load can the spike arrester and filter support, can I plug a multiple outlet Power Board into the device?

- I have an Earth Leakage Circuit Breaker on my house, why do I need anything else to protect?

- The electrician who installed my ELCB has recommended and fitted a Surge Protector on the distribution board and says that’s all I need, but having read the info on your website there seems more to it, what should I be doing?

- I have a complete Home Office with PC, and a new Flat Screen Monitor and Multi Function System; I have the Pro Series CMP Ultra 2 single outlet filter and originally connected my PC to that, what about the other equipment?

- Can I use a double adapter on the protective devices?

- I have a Note Book Computer that has an external AC/AC Power Pack and I was given to understand that I don’t need Power Protection, but a colleague had his Note Book destroyed recently while travelling. What can you recommend?
How does the Professional Series Filter Protect?
The Professional Series Power Filter range is a combination of a Spike Arrester and Power “Sifting” Device, featuring a circuit design comprising of low clamping voltage, very fast reaction time Metal Oxide Varistors (MOV’s) to capture and divert spikes. Completing the design is a filter circuit containing capacitors and toroids that capture, absorb and dissipate noise.

The Power Filter protects by diverting potentially damaging high voltage spikes to earth and the filter circuit cleans (sifts) the power of transient noise by dissipating the transient pulses.

Protection is across all three conductors (Common and Differential Mode) that under normal operating conditions do not interrupt the supply voltage. The design is not amperage dependent to activate and protect; however a reliable Earth is required for optimum performance.

The rapid reaction time, high-energy dissipation and robust performance minimises voltage let through reducing the risk of damage from high voltage spikes and transient power disturbances. Ideally suited for protection of sensitive electronic equipment including computers, electronic games and home theatre.
