The XTLD, Dual Voltage Isolated Power Panel, is a single panel with one transformer and two different ungrounded
output voltages. Each secondary winding will have it's own load center and Line Isolation Monitor.
Typical secondary voltages are 120/208 volts but other voltages are available, 120/240, 110/220, 120/120. This panel is designed to supply ungrounded power for one operating room. It can be mounted inside or outside the room. When mounted outside the room, two remote annunciators will be required inside the room.
The 208 volt circuits are used to power laser, x-ray or where 208 volt ungrounded power is required. The 120 volt circuits are used to power 120 volt appliances found inside the operating room. It is not recommended to put the overhead fluorescent lights on this panel due to the high leakage of the ballast. Overhead lights should be on grounded power.
The Dual Voltage Isolated Power Panel is factory equipped with up to 16 each two-pole branch circuit breakers for the 120 volt winding and two each two-pole branch circuit breakers for the 208 volt winding.
Receptacles can be mounted on the front but remote mounting is recommended for location convenience. Six each 120 volt duplex, six ground jacks and two each 208 volt receptacles are the maximum that can be mounted on the front of the panel. If two 120 volt panel boards are required, no receptacles can be on the front.
The KVA of the transformer is determined by adding the KVA of the 120 volt winding "A" and the KVA of the 208 volt winding "B".
The combined KVA is the KVA size of the transformer. The maximum total KVA is 25 KVA per UL. Specify the KVA of "A" and "B" windings. Example: if 15 KVA will be required for 208 volt winding and 10 KVA for the 120 volt winding, the overall size is 25 KVA. If 10 KVA is required for both then the size of the transformer is 20 KVA. All transformers are single phase only.
