1405A

1405A is a 100W triple output switching DC power supply designed for accuracy, compactness, and portability. Equipped with rotary encoder knobs for precise voltage and current adjustment with a 4-digit LCD for clear readout. They operate in both constant voltage (CV) and constant current (CC) modes, with automatic crossover based on load conditions. It is passively cooled for quiet operation and suited for benchtop or embedded applications. All three outputs (one variable and two fixed) are fully isolated, allowing flexible configurations for a wide range of test and development scenarios. The main output is adjustable to 36V, while auxiliary outputs provide fixed 3.3/5V DC and 12V DC. Isolation enables series or parallel connections for generating bipolar, stacked, or higher voltage rails, making these supplies ideal for troubleshooting multi-voltage circuit boards.
