Battery Discharger, Voltage Regulator, Resistor Bank, And MOSFET

Deep discharging of batteries and battery packs is important in a number of applications. However, there are some issues associated with this process. One issue is the voltage recovery effect. To overcome this, you can use a discharge resistor bank. This unit can help you monitor the condition of your batteries and battery packs.

Battery Discharger

A battery discharger is a device that allows you to test the state of charge (SoC) and the depth of charge of your batteries. It does this by applying an electronic load to a battery and monitoring the results. These devices can be portable or stationary and can offer several different discharge modes. The internal resistance of a battery increases as it discharges. This causes the battery to lose voltage and end up at a lower than expected voltage. To prevent this from happening, you can use a discharge resistor to reduce the voltage of your battery.

A discharger is a high-quality product that uses copper and nickel alloy wire grid elements and has a cast aluminum shell. It is also designed to be easy to handle. It features a built-in display to record all of your data and offers a variety of discharge options, including constant current, constant power, and preset load profiles. It can also stop testing automatically when the test time, capacity, and protective voltage are out of range.

Resistor Bank

A resistor bank is a group of power-rated resistors connected in parallel. It is useful for discharging battery systems and testing generators, UPSs, and turbines. It can also be used to simulate inductive loads. These are typically used in electrical test labs and in industries. It can be made with different power ratings and a variety of switches. It is important to choose the right type of resistors for your application. For example, axial leaded non-inductive bulk ceramic resistors are ideal for high peak power applications. They are able to handle large energy pulses without overheating.

Other types of resistors include edgewound and round-wire styles. These resistors are suitable for continuous-power applications, where the resistance value is largely determined by the Watt (voltage x current) rating. Both of these load resistor bank can be thermally enhanced for higher power dissipation. They are also capable of handling heavy-duty loads. They are compact, quiet, and modular. They are also a good choice for applications in harsh environments.

Voltage Regulator

A voltage regulator is an integrated circuit that creates a constant output voltage even if the input voltage changes. They are commonly used in power supplies to provide a stable DC output to other electronic components in the system. Voltage regulators have several key performance parameters that must be considered when selecting them, including efficiency, quiescent current, and voltage accuracy.

The UBA Battery Discharge Tester allows the user to continuously record valuable data during the discharge process. This data is then transmitted to a PC and saved for analysis. It also provides a safe discharge process by avoiding red heat and by regulating the discharge current. This unit is designed to perform periodic discharge tests on station batteries. Its robust design consists of Copper-Nickel Alloy wire grid elements supported on S.S. tie rods and insulated from each other with Micanite tubes, washes and ceramic formers. It is mounted on a base and equipped with castors for easy mobility.


The MOSFET (Metal-Oxide Semiconductor Field-effect Transistor) is a type of transistor that can change its conductivity with an electrical voltage. It is often used in digital and analog electronic circuits to switch or amplify signals. The MOSFET has insulating silicon dioxide and a gate that allows charges to be controlled and isolated.

When the voltage on the gate is high, it creates an electric field that draws free electron charge carriers to the surface of the semiconductor and insulator. This forms an inversion layer, which opens the channel between the p-doped and n-doped regions of the chip. The current can flow through the inversion layer, which is why the MOSFET is able to act like a switch. The MOSFET can be purchased in different packages, including through-hole mounts that feature component leads inserted into holes and secured to printed circuit boards (PCBs). The number on the package indicates whether the device is in depletion or enhancement mode.


Battery Discharger Load resistor bank is used to perform periodic discharge tests on station batteries. The resistor unit is constructed with Copper-Nickel Alloy wire grid elements. The resistor is robust and allows fast natural cooling. To configure the circuit open a Battery Analysis routine in UBA Console. Select the External load device and control.
