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
