ISDT MP305 150W Color Touch Screen Multi-functional linear DC Regulated Power Supply
by ISDT

The ISDT MP305 150W Multi-Functional Linear DC Regulated Power Supply (Model: MP305A-US) is an ultra-compact, precision benchtop power supply and programmable lab instrument engineered for electronics engineering, hardware prototyping, and field testing. Designed around an advanced dynamic-tracking linear regulation architecture, the MP305A achieves reference-grade low-noise performance with output ripple under 2mVrms and 3mArms, delivering the clean signal characteristics of a traditional heavy linear bench supply in a chassis roughly one-eighth the size.

The MP305A-US operates from a universal 100V–240V AC mains input via a rear 3-pin IEC socket. It features a primary front MR30 high-current DC output capable of delivering 0–30V and 0–5A up to 150W, complemented by an independent front USB Type-C Power Delivery port capable of up to 140W (supporting PD3.0, PD3.1, PD3.2, and PPS) with E-Mark chip cable interrogation. Interfaced through a 2.8-inch full-color capacitive touchscreen and a digital rotary encoder, the MP305A provides real-time voltage/current curves, automated CC/CV switching, multi-chemistry battery charging (LiPo, LiHV, Li-ion, LiFe, NiMH, Pb), and programmable 100-point output sequences controlled locally or across platforms via Bluetooth and USB.

Key Features

• Hybrid Linear Regulated Architecture: Combines high-efficiency dynamic pre-tracking with linear output regulation to ensure ultra-low noise (<2mVrms ripple) and fast transient response (<90µs).

• Ultra-Compact CNC Aluminum Enclosure: Measures 138 x 86.5 x 70 mm and weighs 628g, reducing benchtop footprint by up to 85% compared to conventional transformer-based linear power supplies.

• Dual Output Architecture: Features a front MR30 connector delivering 0–30V / 0–5A (150W max) and a front USB-C PD3.1 port delivering up to 140W with PPS and E-Mark protocol readout.

• Interactive 2.8" Color Touchscreen & Encoder: High-contrast IPS capacitive display offers numerical readouts, analog meter emulations, and real-time V/I oscilloscope-style wave graphs.

• Programmable Output Sequences: Supports 10 memory groups with up to 100 customizable voltage/current/time steps per group for automated hardware stress testing and simulation.

• Universal Multi-Chemistry Battery Charging: Operates as a precision battery charger supporting 1–6S LiPo/LiHV/Li-ion, 1–8S LiFe, 1–20S NiMH/NiCd, and 1–12S Lead-Acid packs.

• Cross-Platform Telemetry & Control: Onboard Bluetooth and wired USB connectivity enable full parameter control, data logging, and OTA firmware updates across Windows, macOS, Linux, Android, and iOS.

• Integrated 1/4"-20 Threaded Mount: Standard tripod mount on the base enables flexible mounting on articulated arms, workstation rigs, or mobile field stations.
