Physical Characteristics and Installation
This power supply module weighs approximately 1.65 kg for stable rack mounting. Its dimensions measure 250 mm x 100 mm x 185 mm for Procontic chassis slots. First, slide the 07 NG 66 R2 into the dedicated leftmost rack position. Then, connect the AC input wires to the terminal block. Finally, secure the module using the top and bottom retaining screws. LED indicators show AC present, DC output status, and fault conditions.
Output Specifications and Power Distribution
The 07 NG 66 R2 delivers 5V DC at 10 A for all logic circuits. A separate 24V DC output provides 3 A for field devices and sensors. The total combined output power reaches 122 W. Consequently, this module can support fully populated Procontic racks. The 5V and 24V outputs share a common return for simplified wiring.
Protection Features and Hold-up Time
Built-in overload protection shuts down the output during excessive current draw. Short-circuit protection activates instantly to prevent damage. Over-voltage protection clamps the outputs during internal faults. A 20 ms hold-up time maintains output during brief AC power interruptions. Therefore, the 07 NG 66 R2 keeps your system running through momentary voltage dips.
