Test Equipment Description

The Noiseken LSS-15SC is the lightning surge simulator conforming to "Surge Immunity Test Requirements" of IEC Pub. 801-5. This simulator is provided with a combination wave generator and is also provided with an AC/DC line injecting unit as a surge injecting unit.

Waveform Generator
The LSS-15SC is provided with a surge generator, namely a combination wave generator prescribed by "Surge Immunity Test Requirements" of IEC Pub. 801-5. The combination wave means a voltage waveform of 1.2/50 μ s when the circuit is open and a current waveform of 8/20 μ s when the circuit is closed.

Injecting Unit
Surge Immunity Test Requirements of IEC Pub. 801-5 prescribe several kinds of coupling/decoupling networks. The LSS-15SC is provided with an AC/DC line injecting unit.

(1) The AC/DC line injecting unit has a power capacity of AC240V 20A single phase and DC60V 20A for equipment under test. This unit is used to inject a combination wave to an AC/DC power line.

(Note) It is necessary to receive power from an external AC power supply or DC power supply.

Components of LSS-15SC
The LSS-15SC consists of Control Unit, Surge Generator and AC/DC Line Injecting Unit, which are set in the rack (1800mm in height x 555mm in width) with casters.

Note: It is necessary to receive power from an external AC power supply or DC power supply.

Appearance of LSS-15SC

Control Unit
Use to control a surge output in accordance with settings of surge output conditions. Surge output conditions can be set on the front operating panel. It incorporates a high-voltage power supply for surge generation.
Surge Generatos
Used to generate combination waves.
AC/DC Line Injecting Unit
Used to inject a combination wave to an AC or DC power line. Injection mode can be set on the right side of the AC/DC line injecting panel.
