Safety Instructions
Review the Installation Manual before proceeding.
If there are any questions regarding safe installation or operation &
performance please contact us at: [e-mail].
Prior to any handling, the Power Supply must 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 should perform
installation.
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 that there is no voltage at the P.S.
Only a licensed electrician should install the P.S.
Ensure that all cables are dry and wet-protected.

Overview:
T-Former is a 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 about double the lifetime of
legacy Ferro-resonant products, it delivers at least 5% energy savings
compared with standard systems. Its modular optional design enables an
upgrade of the T-Former to UPS by adding a compatible ONLINE DC-AC inverter
/Charger. This 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 the line voltage
and compensates for any changes,
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 near buildings. T-Former is
designed to work at a wide range of
temperatures and humidity without
maintenance, at full power capacity. 100%
of Safecom's T-Formers undergo rigorous
and repeated quality testing.

•Technology
•The TFPS series Dual Port CATV P.S with utilizes novel & US Patent AC/AC variable
ratio transformation provide ultimate voltage regulation and pure sine voltage
output at all loads. Input & output Voltage are completely isolated line
conditioning enabling changing gears at O time "zero crossing". This smooth online
transformation between gears provides clean AC pure sine voltage without any RF
noise.
•An extra feature of the T-former Novel P.S is its SOFT STARTUP, solving the most
hazard problem of Ferro based P.S: the Inrush current. This innovative solution
controls the current level during start-up and prevents the circuit breaker from
falling during startup or utility power interruption.
•The system also has electronic overload protection, protecting the network and
minimizing fuse blow when momentary short circuits occur.
•Safecom T-Former P.S offers the most efficient technology with almost 95% efficacy
at a wide range of loads. It saves electricity and maintains the transformer and its
electronic parts at cold temperature, making it the most reliable P.S with unlimited
lifetime.
•Unlike the Ferro P.S, characterized by noise and vibration, the new T-former P.S is
completely silent, with no vibrations, making it suitable for installation near
buildings and homes. Block Diagram T-Former P.S

Voltage configuration
Safecom TF-PS series offers input & output voltage-level flexibly. Technicians can
easily configure the optimal input voltage level and recommend output
voltage levels for supplying power to the network.
1) Ensure utility power is OFF when changing voltage configuration at input &
output.
2) Changing the settings is done by moving input & output cables from one port
to another. The cable is fastened by a powerful spring. To release it, simply press
the lower point using a screw driver.
3) This configuration insures reliable connections for life, without any possibility
of losing the connection.

Installing TFPS –Outdoor
The SC-TFPS outdoor series non-standby power supplies are designed to be
mounted by separate brackets on a wall or on a pole.
When installing a TF-PS on a pole, an approved mounting strap must run through
the mounting slots of the back bracket. When installing on a wall, use two >8 mm
screws to fasten the bracket to the wall.
After bracket is fastened to the wall, hang the PS on the bracket and tighten the
screw at the bottom of the P.S in order to lock it.

Troubleshooting and Repair
The T-former P.S is designed to be the most reliable P.S that can be used for
unlimited time at all weather conditions, even at maximum load.
The Power supply has slow-start circuit and overload protection to prevent the
most common failure at the network such as inrush current that switches OFF
the circuit breaker, or blows the fuse as a result of overload or short circuit.
This guide explains the possible, yet rare symptoms:

Solution Reason Symptom
The network must be
monitored and the failure
cause must be removed
1) P.S. was shut down due
to overload current short-
circuit or a burnt fuses.
