DX-1S DIGITAL PABX - Installation Manual

8.DX-1SU

8.1DESCRIPTION

DX-1SU is a small version of DX-1S, which has maximum capacity of 160 ports. The DX-1SU had
integrated the AC / DC power supply inside the system cabinet, no SPS-4820 or other AC / DC power
supply is required.

The DX-1SU is aimed to provide a cost-effective solution for a system requires less then 160 ports. Since
DX-1SU uses the same software of DX-1S, it includes most of the features of DX-1S.

The main difference between DX-1S and DX-1SU are system cabinet and power supply.

8.2DX-1SU MODULE SYSTEM CABINET

DX-1SU cabinet has the same dimension of the DX-1S cabinet, but the right area inside the cabinet is
reserved for the DX-1SU power supply.

DX-1SU has a smaller Module Mother board, which can accommodate 10 peripheral card at most. So that
it has a maximum capacity of 160 ports per system.

8.3DX-1SU POWER SUPPLY

The DX-1SU Power Supply is a battery backup AC/DC power supply and it should installed in the
dedicated space inside the DX-1SU cabinet. The DX-1SU Power Supply has the function of both AC / DC
power supply and PSC as in DX-1S. The Power Supply inputs 220 AC power, generates DC +5V, -5V,

-48V and Ringing voltage for the System and charges up the backup batteries. Once the AC power is
failed, the Power Supply will switch to the backup batteries automatically and draw the current to the
System without interruption until the AC power is recovered.

8.3.1BUILT-IN INPUT SURGE PROTECTOR

The Power Supply has a Built-in Surge Protector for the AC power input. The surge protector will filters
out the high voltage surge in AC power line and protects the Power Supply from damage.

8.3.2OUTPUT OVER-VOLTAGE PROTECTION

The power supply includes output over-voltage protection. If the 48V output voltage is higher than 60
voltage, the power supply will shut down automatically. It requires manual reset the power supply by turn
off the system, wait about 1 minutes and then turn it on again.

If a backup battery is connected to the Power Supply, the Power Supply will switch to the backup batteries
automatically when the power supply shut down.

8.3.3BATTERY OVER-DISCHARGE PROTECTION

The Power Supply also includes output low-voltage protection to protect the backup batteries from over
discharge. Once the AC power is failed, the Power Supply will switch to the backup batteries automatically
and will draw the current to the System without interruption until the AC power is recovered. The
protection circuit will monitor the output voltage. If the output voltage is under 42V, the protection circuit
will cut off the battery to avoid damaging the batteries. The “L.V.” red LED will light up. If the AC power
recovers and the power supply will charge up the batteries.

8.3.4AUTO-RANGING VOLTAGE

The Power Supply has the Auto-Ranging Voltage capability for input AC voltage. It will accept input
voltage of 85 ~ 132V / 170 ~ 264V.

8.3.5LED INDICATION

The DX-1SU Power Supply has 5 LEDs in the front panel. The first four green LEDs indicate the +5V,

-5V, -48V and Ringing voltage output condition. If the LED turn on, it indicates the output from the Power
Supply is normal.

The fifth red LED is “L.V.” – Low Voltage cut off indication. When it turn on, it indicate the battery output
is under 42V and the batteries are cut off to avoid damaging the batteries.

8.3.6COOLING FAN

The DX-1SU Power Supply has a cooling fan inside for cooling purpose. The cooling fan will turn on
when the Power Supply temperature is high enough (require cooling). When the Power Supply is cooling
down, the fan will turn off automatically.
