Description
The FNIRSI DPS-150 is a compact, high-performance programmable DC power supply delivering up to 150W of clean, regulated output with 0.01V voltage and 0.001A current resolution across a 0–30V / 0–5A range. Featuring CC (Constant Current) and CV (Constant Voltage) operating modes, a 2.8-inch IPS color display with 90° flip capability, 6 preset memory slots, PC connectivity, and 8 built-in safety protection mechanisms, it packs lab-grade power supply features into a palm-sized unit weighing just 178g. For electronics engineers, hobbyists, repair technicians, and students across Karachi and Pakistan, the DPS-150 is an ideal bench or field power supply that can be powered by a PD-compatible laptop charger, power bank, or DC adapter — no mains-powered brick required.
Why Choose the FNIRSI DPS-150?
In Karachi’s electronics workshops, university labs, and DIY repair benches, a reliable regulated DC supply is a daily essential. The DPS-150’s ability to run from a USB-C PD fast charger or power bank makes it uniquely portable — you can power it from your phone charger or laptop adapter and use it anywhere. Its <20mV output ripple, 96.3% full-load efficiency, and comprehensive 8-point protection make it safe for powering sensitive modules, charging lithium cells, testing sensors, and programming microcontrollers.
