Made in Mainland China.

Key Features

• Versatile Input Compatibility: Dual Type-C and DC barrel input interfaces support a wide 5–32V DC input range, giving you maximum flexibility at your workbench or in the field. PD 3.0/2.0 and BC 1.2 protocols supported.
• Precise Voltage & Current Control: Hardware constant current (CC) and constant voltage (CV) modes with fine-tuning from 0V/0A. Set voltage in 10mV steps and current in 1mA steps — perfect for sensitive electronics.
• High Efficiency Architecture: Up to 97% full-load efficiency at 100W (30V, 3.334A). Ultra-low ripple (≤2mVrms / 10mVp-p voltage; ≤1mArms / 3mAp-p current) keeps your devices stable and noise-free.
• Smart Programmable Presets: Store and instantly recall up to 10 output preset groups — eliminate repetitive setup time on recurring tasks and switch configurations in seconds.
• Comprehensive Protection Suite: Input undervoltage & reverse polarity protection; output overvoltage, overcurrent, overload, overtemperature, and reverse connection safeguards — your equipment stays protected in any scenario.
• 2.4-Inch Color Display: Clear, full-color screen shows real-time input/output voltage, current, and power at a glance.

Frequently Asked Questions

Q: What input sources are compatible with the DPS100 programmable DC power supply?

A: The DPS100 accepts both a Type-C input (supporting PD 3.0/2.0 and BC 1.2 protocols) and a standard DC barrel input, with a wide input range of 5–32V DC. This means you can power it from a laptop charger, USB-C PD adapter, or virtually any regulated DC source within that voltage range.

Q: Can I use the DPS100 adjustable voltage regulator for charging lithium batteries or testing sensitive electronics?

A: Yes. The DPS100 offers hardware-controlled constant current (CC) and constant voltage (CV) modes with fine resolution (10mV / 1mA), making it well suited for charging lithium batteries, testing microcontrollers, powering LED arrays, or running precision circuit experiments — all with comprehensive overcurrent, overvoltage, and overtemperature protection built in.

Q: How do the 10 programmable preset output groups work?

A: The DPS100 allows you to save up to 10 custom voltage/current configurations in memory. At any time, you can instantly recall a saved preset with a few button presses, eliminating the need to manually re-enter settings for repeated tasks — ideal for production testing, hobby projects, or classroom lab setups.

Q: What protection features does this mini switching power supply include?

A: The DPS100 provides a full suite of protections: input undervoltage protection, input reverse polarity protection, and output-side overvoltage, overcurrent, overload, overtemperature, and reverse connection protection. These safeguards help protect both the unit itself and connected devices from accidental damage.
