09 OPTIONAL ACCESSORY

9.1 PS-60 Regulated DC Power Supply
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/SG 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/SG and the front panel can be
positioned on the same panel height of the TS-590S/SG using the stand on the front bottom. (Since the length of the body
differs, the angle of inclination is slightly different.)
