GTO Transformer RB570

GTO Replacement Transformers:
Follow this guide to order the proper transformer for your GTO powered gate. There are 5 choices and not all will work with all GTO gate operators.

Background Information:
GTO, Inc. upgraded all operators in March 2000 to comply with UL325 safety requirements. With this and other changes, different transformers were required than were included on original equipment. More importantly, operators made after March of 2000 are different and require different transformers. If you bought your operator after March of 2000, chances are you have the new upgraded UL325 operator. It is possible to have purchased it after March and have an older style. Vendors were allowed to sell their existing stock and the time of the change. If you bought it from Hoover Fence after March 2000, you have the new UL325 regardless of which operator model you purchased. One way to tell the difference in the old style and new is the new one has a warning beeper feature. Also, the new UL325 had a change in the way the control cables connected. The old style had plugs on the end that connected to the control box. The new style has no plug on that end. It has bare wires that slide into the control box and connect to a terminal board. Older style transformers will work on new operators, but newer ones will not operate on older ones.

Note: Use this transformer for all versions of the PRO3000, PRO4000, PRO2500, PRO1500 as well as the Mighty Mule FM500/502 and FM350. Also used for all newer PRO2000 or SL1000 gate operators. They will have a warning beeper feature built-in to the control box, whereas the older ones do not. Number of cycles per day usage does not matter.
