Functions

LCD display with backlight – clear visualization of output current and settings.

Manual mode – simple and quick output current adjustment by turning the control knob.

Dynamic mode – ability to program up to 9-segment curves, setting time, initial and final current.

Memory function – saved settings remain even after the device is turned off.

Protection functions – reverse polarity protection, reliable operation without risk of damage.

Usage

For home user: can be used as a learning tool for electrical tests, LED or other small load testing.

For engineer: suitable for laboratory work, PLC, control systems and sensor simulation, process testing before real integration.

For electrician: ideal tool for commissioning systems on-site – allows checking wiring accuracy, signal reception, load response.

For industry specialist: used in processes requiring standardized 4–20 mA signal generation or load testing.

Pros

Clear LCD display with backlight – convenient in any conditions.

Two operating modes – manual and dynamic, allowing both simple and complex tests.

Precise adjustment with digital encoder – durability and reliability.

Memory function – no need to reset parameters.

Reverse polarity protection.

Cons

Requires external power supply (15–30 V DC).

Dynamic mode setup may be complex for beginners.
