TS-590S CONTENTS 67
9 OPTIONAL ACCESSORY
PS-60 is a regulated DC power supply designed for amateur transceivers.
The power supply adopts a switching module that accepts the input AC Voltage in the range from 90
V to 264 V. Though the power supply unit is compact in size (W 173.5 mm x H 95.5 mm x D 204.3
mm or W 6.83 inch x H 3.76 inch x D 8.04 inch) and lightweight (2.6 kg, or 5.73 lb), it has a capability
to stably supply the power source enough to the transceivers including the TS-590S for 100-W class
output power.
PS-60 has a higher load efficiency (85% typical with rated load current at 100 V) than the
conventional transformer-type power supply units and conforms to your local energy regulations,
enabling ecological and economical operation.
PS-60 received safety certificates in many countries in the world and incorporates the following
protection features. Furthermore, the power supply has gone through safety and durability tests
conducted according to Kenwood’s criteria to ensure your safe operation.
<Overcurrent Protection Feature>
If the load current exceeds 27 A, the output voltage droops and the output becomes intermittent to
protect the main body.
<Overvoltage Protection Feature>
If the output voltage exceeds 18 V due to any failure, the supply of the power source stops so as to
protect the connected device.
<Temperature Protection Feature>
The internal temperature is always monitored and if an aberrant value is detected, the supply of
the power source stops so as to protect the main body.
The unit is equipped with a quiet cooling fan that starts running once the internal circuit detects the
temperature exceeding a certain level.
The power supply unit has an external appearance design that matches the TS-590S and the front
panel can be positioned on the same panel height of the TS-590S using the stand on the front
bottom. (Since the length of the body differs, the angle of inclination is slightly different.)
