| This
automatic voltage regulator provides stable power even when the ac mains
or back-up generator voltage is extremely low or high.
Typical
applications for the SLc Series
SLc Series four stage tap-switching
power conditioners provide
low-cost ac line protection for computers, point-of-sale terminals,
copiers, data acquisition and control systems, as well as other data
processing equipment. SLc’s can also be used to protect low-cost stand-by UPS to prevent
discharge of UPS batteries due to low- or high-voltage transfer to inverter.
Key SLc Series
stabilizer benefits
TSi Power’s SLc Series regulated
output protects switch-mode power supplies from failure caused by
unstable ac mains. SLc provides three-way surge protection and reduction
of surge voltage.
The SLc line conditioner can be used
between a UPS and the ac mains to provide even greater protection for
the connected equipment, while saving the UPS internal batteries for
true black-outs.
How the SLc
Series four stage automatic voltage regulator works
The SLc Series incorporates a
four-winding auto-transformer, which provides four levels of line
regulation: two boost-stage and one buck-stage. Even when the input
voltage varies between 75 to 150V, the output is regulated to within 105
and 130V, well within the range of most equipment.
SLc operation is monitored by four status LED’s,
indicating normal, boost 1, boost 2 and buck stages of voltage
regulation. The front panel power switch turns the SLc on and supplies
power to the equipment. |
