Feature

This solid type equipment is designed with only semi-conductors, consumes low electric power, thus, we can operate it at low operation cost with easy and simple maintenance in safety.
Complete Module Construction. Each module is separate in draw type compartment sliding forward for easier investigation on parts.
Total output is made with aggregated combination of 4modules (HSS-3000S) and 6modules (HSS-5000S). therefore, even in case of failure in some of modules, it operates steadily at steadily lower output power

Functions

It is equipped with circuit elimination hums and noise while compensation distorted waves. Thus it proves good quality transmission
It is easy to set wave bands for 12CH or 128CH, and output levels are adjustable by channel.
Output level is controlled by CPU to make accurate adjustment and to prevent mechanical parts from wears by smooth turning.
All functions for remote control operation are built-in. Therefore, if it is installed optional Remote control unit, remote control operation is possible by Modem.
It has 4-step protection circuits from over-temperature and thunders.
Every unit has individual protection circuits. And it is easy to do maintenance works, as LED shows green for normal condition and red for abnormal condition.
It has smoke and over-temperature sensors, which make power-off automatically if they sense such environment.
Cooling fan is operating when transmitting and it is off when idle to save power cost and enhance parts life.
Output efficiency monitoring and protection functions are equipped in order to avoid malfunction coming from mistake in control by operator.
It has Keying protection function in case of trouble in transmitting.
it has surge protection against over-voltage and over-current.
