We offer voltage regulators with shunt resistance that protect the power source from voltage spikes. They are primarily designed for power consumption for a maximum of a few seconds. The boards are designed to clamp infrequent and short pulses. Longer voltage spikes above the setting the regulator will destroy in a few milliseconds. Let's choose the right one for our circuit. If you have any questions, our technical department is at your service.

Voltage regulation
What is a voltage regulator? It is a circuit whose task is, as the name suggests, to regulate the voltage and thus stabilize the voltage at the output. When a reliable voltage source is required, we reach for example for an inverter with a shunt resistor. Its construction is very simple. It works on the principle of negative feedback. The advantages of linear regulators are low electromagnetic interference and noise, constant output voltage and low purchase cost.
Types of regulators
Regulators can be roughly divided into two types - series voltage regulators and shunt resistor inverters. A series regulator has a variable transistor whose resistance varies on the input voltage and keeps the output voltage constant. The shunt regulator works similarly to the series regulator, and all excess is grounded. Shunt resistor converters are mainly used for precision current limiters, error amplifiers or voltage monitoring.
Setting up the regulator
To check the voltage of any shunt regulator or potentiometer voltage setting, apply a higher voltage using a current limiting resistor of several hundred ohms and measure the voltage on the regulator. Inverters with a shunt resistor should be set to approximately 10% above the supply voltage. There are regulators with varying values available in our store. Every electronics engineer will find something for himself. If you have any questions or doubts you can always contact us - we will be glad to help!
