PRT-CTRL-SE
Protege SE Integrated System Controller
Installation Manual | June 2017
Warning: The total combined current must not exceed a maximum of 1.7A if a 37/40VA transformer is
used, or a maximum of 2.5A if a 60VA or greater transformer is used. The transformer can be
damaged if the total combined current exceeds its capability.
The total combined current is the sum of the operating current, charging current, DC Outputs (AUX1
and AUX 2) and Lock - Bell/Siren (B1 and B2) Outputs.
Please refer to the following Current and Validations Examples for more details.

The isolated communications interface on the Controller uses full galvanic isolation to prevent ground
loop noise and cross phase ground differential. This is a very important feature of the product family
and the correct connection of power to this isolated section will ensure the correct operation of the
communications network.

Current and Validation Example 1
The example shown below refers to the specifications needed to help ensure the correct installation of the
Protege Controller. Specifications have to be validated to ensure that individual maximum currents and total
combined current are not exceeded.
