Welcome to the PowerMan Web Site. Thank you for visiting us. PowerMan UPS's have been manufactured in South Africa since 1984, making us the oldest brand in the country. Our UPS's have been designed and tested to suit the unusual conditions that are found throughout our magnificent continent. If there is one thing that can be guaranteed it is that no electricity supply will be stable at all times. With today's business operation being dependent on computers, and other electronic equipment, steady power is essential, and ultimately the user is responsible for this. This is where we come in. There are many different problems that can be experienced and many different types of protection available on the market. The PowerMan range of power protection and generation equipment offers a solution to all types of power problems from surges and spikes to complete power failures

Some of the problems you can expect are :

SPIKES : A spike is an instantaneous severe increase in voltage (normally 100 % more than nominal voltage). Electronic equipment in the path of a severe spike can expect to have blown components in the power section. Typically a spike would be caused by either a lightning storm or when power is restored after a failure.

Solution : Lightning Protection Device (LPD) or a Constant Voltage Transformer (CVT).

SURGES : A surge is a short increase in voltage (normally 20 % more than nominal). While not causing instantaneous damage surges can stress delicate components and cause premature failure. Surges can be caused when heavy machinery such as welding equipment or a lift stops working.

Solution : Constant Voltage Transformer (CVT) or an On-Line UPS

NOISE : Technically referred to as electromagnetic interference and radio frequency interference (EMI/RFI) . Electrical noise disrupts the smooth output one expects from the mains. Noise can cause glitches and errors in programs and data files. Many things can cause noise on power lines such as lightning, generators, industrial equipment, fluorescent lights etc.

Solution : An EMI/RFI Line Filter or a Constant Voltage Transformer (CVT) or an On-Line UPS

DIPS : Dips, which can also be referred to as brownouts or sags, are short decreases in voltage levels (normally 10 % less than nominal). Dips can be caused by the same type of equipment that causes spikes and surges, but voltage changes are induced by switching units on rather than off. A dip effectively starves a computer of power and can cause amongst other things locked keyboards and unexpected system crashes.

Solution : Constant Voltage Transformer (CVT) or an Off-Line UPS (with AVR) or an On-Line UPS

BLACKOUTS : A blackout is a total loss of mains power. This could be caused by an internal failure such as a circuit breaker trip out or a general power failure where an entire power grid could be out. Depending on the type of software in use a blackout could cause irreparable damage to data files and would certainly result in the loss of any current work.

Solution : An On-Line UPS or an Off-Line UPS
