Power Relays, Over 2 Amps: DSP1-L-DC5V Application Field and Working Principle

DSP1-L-DC5V is widely used in industrial applications, since it is a high current power relay with a heavy load switching capacity higher than 2A. It is rarely used in lighting or home appliance control since it is able to handle a high current.

The DSP1-L-DC5V is a standard single-phase power relay, also known as a short-time relay, purpose-designed for the automatic control of an A.C supply for single-phase and three-phase systems. It is suitable for intermittent service and widely used in a wide range of applications.

The operating system of the relay is based on a timer which uses a device temperature sensing resistor, often referred to as "HTR" (Heat Transfer Reliable). The timer causes the relay to stop responding when its temperature reaches a certain level. The contact operation also depends on an external load, connected to the relay. As the current flowing through the HTR is proportional to the current through the external load, the timer will be triggered whenever the HTR temperature reaches a certain level.

In order to prevent the overloads, the DSP1-L-DC5V will automatically switch off the power supply when the current draw exceeds the set limit. The user shall set the relay\'s trip current in order to protect the load from overheating. The reset is done with a manual knob, which allows the user to select the desired current level. The power relay is provided with a reset button, which allows the user to reset the timer. The power reset button must be activated within 10 seconds after the timer has beend triggered in order to ensure proper operation of the relay.

The TRI-CTRL function is a series of additional features built into the relay that allow it to be used in switchgear and running-gear applications. When the TRI-CTRL function is enabled, the relay will be able to switch from open circuit to closed circuit when the TRI-CTRL limit has been reached. The TRI-CTRL function can be used to prevent over-load or under-load of equipments connected to the power supply.

The DSP1-L-DC5V is designed for high efficiency and energy saving. It is able to handle a wide range of current ratings at a maximum switching capacity up to 2A. The contact materials of the relay are silver-gold alloy, which ensures long performance life and reliability. Furthermore, the contact point is armoured with moisture proof rubber to ensure good performance in hostile industrial applications.

In conclusion, the DSP1-L-DC5V is a reliable and powerful power relay for high current loads. Its unique TRI-CTRL function further increases its versatility by protecting the connected equipment from overload and under-load situations. It is suitable for a wide variety of industrial applications, providing excellent performance and efficiency.
