fuse. The unit can be powered from either a standard 115 or 230 VAC source. A rack-mount accessory is available.

Note: The KTP-24-8E4 can be used as a standard 230 VAC source.

CAUTION:

The KTP-24-8 was designed for indoor applications only. For outdoor units with a heater and fan, use the KTP-24 or KTP­24C.

KTP-24-8 Multiple Output Power Supply Installation Instructions

OPERATION

Each 24 VAC output of the power supply has a resettable fuse that will trip
if the current draw exceeds one amp. In this event, the device on that
output may operate intermittently, or not at all. The fuse will automatically
reset itself when the load is removed from the output.
