Time Delay Relays (TDR) are an essential part of the electrical industry. They are used in automatic control systems to protect electrical circuits from unintended consequences, such as surge current or high voltage, and to delay or prevent operation of electrical devices until certain predetermined conditions are met. The MDE1R05MVA is a TDR specifically designed for applications where it is necessary to delay the activation or deactivation of an electrical load.

The MDE1R05MVA offers various application fields such as electronic lighting control, momentary contact control, control of motor reversal or frequently switched equipment. Its wide supply voltage range and high current ratings make it suitable for both industrial and residential applications. The device is equipped with both adjustable and pre-selected time delay ranges, making it perfect for controlling electrical loads on a predetermined timeline.

The working principle of the MDE1R05MVA is based on electro-mechanical properties: when the device is actuated, a plunger moves a set of contacts that activates the relay. These contacts remain closed for the selected time delay period, and then reopen. This allows electrical loads, such as lights or motors, to be switched off at a predetermined time. The device can be programmed with a built-in timer, or with external timing devices such as a timer, phase angle controller, or control circuit.

The MDE1R05MVA is an advanced TDR that provides a number of features to enhance reliability, safety and time accuracy. It is equipped with a self-resetting thermal relief device to protect against overloads, as well as a short circuit protection system. In addition, the device is equipped with adjustable timing accuracy, allowing for precise timing of the switching of electrical loads.

In conclusion, the MDE1R05MVA is a versatile and reliable TDR designed for various applications. It features adjustable and pre-selected time delay ranges, as well as short circuit protection and adjustable timing accuracy. With its wide supply voltage range and high current ratings, the device is perfect for controlling electrical loads on a predetermined timeline.
