Safety Instructions
Review the installation manual before proceeding.
If there is any questions regarding safe installation or operation &
performance please contact us [e-mail] .
Prior to any handling, the power supply is required to be disconnected
from the Mains.
Only an experienced and authorized technician or electrician who is
qualified to work on the electrical grid while taking necessary
precautions that comply with the electrical code will do handling.
Before Installation:
Make sure that P.S input voltage configuration matches the standard
utility voltage level
Make sure that P.S output voltage configuration matches the CATV
voltage requirements.
Recheck circuit breaker and earth leakage circuit breaker (ELCB).
Connect grounding cable between P.S grounding to utility grounding
point.
Safety:
Prior to installation or removal recheck that utility circuit breaker is OFF
and no voltage at the P.S.
Only licensed electrician is required to install P.S.
Ensure all cable dry and wet protected.

Overview:
T-Former is pure stabilizer sine wave P.S with the highest- efficiency, and most
reliable technology, specifically developed for the advanced operation of line
amplifiers in CATV distribution systems. With around double the lifetime of
legacy Ferro-resonant products, delivering energy savings of at least 5% energy
compared to standard systems. Its modular optional design enables upgrade
of the T-Former to UPS by adding compatible ONLINE DC-AC inverter
/Charger . That helps operators reduce network expenditure at capital as well
as operational levels.
Thanks to its patent-pending sine wave
stabilizer technology, the T-Former's
advanced electronic controller
automatically monitors and compensates
for any changes to line voltage -
eliminating negative Inrush current side
effects resulting from utility power
recovery. In addition, the T-Former
operates in complete silence - solving
noise and vibration problems inherent in
existing products. This is increasingly
important in highly populated areas
where power supply devices are often
mounted nearby the buildings. T-Former
is designed to work at a wide range of
temperatures and humidity without
maintenance, at full power capacity.
Safecom's T-Formers undergo rigorous
quality testing - with fully 100% of the
units repeatedly tested.

•Technology
•The TFPS series, non-standby with the modular UPS option utilizes novel and
patented P AC-AC variable ratio transformation, providing ultimate voltage
regulation and pure sine voltage output at all loads. Input and output
voltages are completely isolated. Line conditioning allows for changing gears
at 0 time (“zero crossing”).This smooth online transformation between gears
provides clean AC pure sine voltage without any RF noise.
•An additional feature of the T-Former Novel P.S. is its Soft Startup, addressing
the most serious problem of Ferro-based P.S: the inrush current. This
innovative solution controls the current level during start up and preventing any
possibility of circuit breaker down during startup or utility power interruption.
•In addition electronic over load protection protecting and the network and
minimize fuse blow when momentary sort circuit occurred
•Safecom T-Former P.S has the most efficient technology with almost 95% efficacy at
wide range of load. It saves electricity and keeps cold temperature of transformer
and electronic parts make P.S most reliable for un-limited life time
•No like noise and vibrating Ferro P.S the new T-former P.S is completely silence with
no noise and vibration enabling to install nearby premises houses or very quite
places without interfere the residential area.

Voltage configuration
Safecom TF-PS serial offer input & output voltage level flexibly. Technician can
easily configure the optimal input voltage level and recommended output
voltage level for supplying power to the network.
1) Ensure utility power is OFF when changing voltage configuration at input &
output.
2) Changing is setting is by moving input & output cables from one port to
another. Cable seizure is by very strong spring. To release seizure simply need to
press the lower point by screw driver.
3) This configuration insure reliable connection for life without any possibly of lost
connection.

Installing an TFPS –Outdoor
The SC-TFPS outdoor series non-standby power supplies are designed to mount by
separate bracket on a wall or pole.
When installing an TF-PS on a pole an approved mounting strap must go through
the mounting slots of the back bracket. When installing on the wall use two >8
mm screws to band the bracket on the wall.
After bracket is will well banded on the wall hang PS on the bracket and tight the
screw at the bottom of P.S for locking P.S.

Troubleshooting and Repair
The T-former P.S designed to be the most reliable P.S that can be use for
unlimited time at most harass environmental such as heating and humidity
even at maximum load.
Power supply has slow start circuit and overload protection to prevent the
most common failure at the network such as inrush current that switch OFF
circuit breaker, or fuse blow cause by overload or sort circuit.
This guide explain the few rare symptoms possible.
