## Description

Automatic step-up/down module for variable power supplies, maintains the set voltage stable regardless of input fluctuations, ideal for electronic projects and as a base for adjustable laboratory power supply. Offers adjustable output with constant voltage and current mode, high current for demanding consumers, short circuit protection and switchable input fuse, low ripple for clean power supply.
Quality automatic step-up/step-down voltage source. Adjustable output. Maintains the output voltage regardless of variations in the input voltage;
Example: at a voltage set at 12V, it remains fixed when the voltage changes between 5 and 32V.
It can be used as the basis for building an adjustable laboratory source.
Quality protection.
Changeable protection fuse on the input.
High frequency and low resistance capacitors.
Constant voltage and current.
LED output error indicator in case of voltage variations, short circuit or other defects.
Supply voltage: 5 - 32 VDC
Output voltage: 1 - 30VDC, adjustable
Output current: 10A MAX, recommended under 8A, 6A for long term, adjustable
Output power: 80W, 130W peaks (above 80, improve cooling)
Ripple output: 50mV
Short circuit protection: Yes
Input polarity protection: No
Output polarity protection: No
Operating temperature: -45 ~ +85 ℃
Dimensions mm: 77.6*46.5*15mm (includes the aluminum cooling surface at the base).
Attention: if the "fault" LED stays on when the power is turned on, check the potentiometer next to the power supply ("low volt cutout"). It sets a fuse that stops the module under a certain voltage.
