Description

Product Overview

The DR-100-24 is a versatile and robust DIN rail power supply that acts as the backbone of industrial control systems.It converts a standard AC input voltage(typically 85-264VAC)into a regulated 24V DC output,which is the industry standard for powering control circuits.With a maximum output of 100 Watts(equivalent to 4.2 Amps),the DR-100-24 is capable of powering a wide range of components simultaneously,from a main PLC module to dozens of I/O devices and field sensors.Its compact form factor saves valuable space within control cabinets,while its high efficiency minimizes energy consumption and heat generation.

Engineered with built-in protections,the DR-100-24 safeguards connected equipment against short circuits,overloads,overvoltage,and overheating.This high level of reliability and protection is crucial for ensuring the continuous operation of critical industrial processes.The power supply features a standard green LED indicator for a quick visual status check and an adjustable output voltage range,allowing for fine-tuning to meet specific application requirements.

Installation and Maintenance

Installation

Before installing the DR-100-24,always ensure that the power supply to the cabinet is disconnected and locked out.The power supply should be mounted vertically on a standard DIN rail to ensure proper heat dissipation through convection.Connect the input wires(L,N)to the screw terminals and the output wires(+V,-V)to the DC output terminals.For safety,ensure the grounding wire is connected to the ground terminal.Verify all connections are secure to prevent loose wiring and potential arcing.

Maintenance

The DR-100-24 is designed to be a”fit and forget”component with a high MTBF(Mean Time Between Failures).Routine maintenance is minimal and primarily involves:

Visual Inspection:Periodically inspect the unit for any signs of physical damage,overheating,or discoloration.

Ventilation Check:Ensure that the ventilation holes on the top and bottom of the unit are not blocked by dust or other debris to allow for proper airflow.

Terminal Tightness:Periodically check the terminal screws to ensure they are still tight and that connections have not loosened due to vibration.

If the status LED(typically green)is not lit,it may indicate a lack of input power or a fault with the unit itself,in which case it should be replaced by a qualified technician.
