This manual describes the features and usage of the Extech 382270 high precision quad output DC power supply. The power supply has four outputs, two of which are fully adjustable and two are semi-adjustable. The two adjustable outputs can be configured for constant voltage or constant current. The two adjustable outputs can be connected in parallel or in series. The 3 digit LED display indicates each of the two adjustable outputs. The two semi-adjustable outputs (one is 3~6.5V/3A and the other is 8~15V/1A) have good stability and ripple factor, and reliable overload protection to protect the unit against overloads or short circuits. This power supply is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
The Extech 382270 is a high-precision DC regulated power supply featuring four outputs. Two outputs are fully adjustable for constant voltage or constant current modes and can be connected in series or parallel. The other two outputs are semi-adjustable with fixed voltage ranges and reliable overload protection. The unit includes a 3-digit LED display for monitoring the adjustable channels.
