The market has been desperately looking for a solution that combines laboratory-grade precision with the intelligent DNA of the internet era due to the increase in demand for mobile work environments and precise electronics repair. The game-changer created especially to address this demand is the MP305 series, a joint venture between PowerPi and ISDT. In addition to redefining the "linear power supply" form factor, it pushes the boundaries of multifunctionality integration.
I. Core Product Breakthroughs
1. A "Linear" Miracle in 1/8 the Volume
Traditional 150W-class linear power supplies typically weigh several kilograms and occupy half of a desktop workspace. The ISDT MP305, however, utilizes innovative circuit design to shrink its physical volume to just one-eighth that of comparable power supplies, all while retaining the core advantages of true linear regulated output.
· Ultra-Low Ripple and Noise: Voltage noise < 2mVrms; Current noise < 3mArms.
· High-Precision Response: A response time of < 90 microseconds ensures that—when powering sensitive components such as precision logic boards or audio decoder chips—it delivers a current as pure and clean as that from a battery.

2. A/B Dual Versions: Covering Every Work Scenario
· MP305A (AC-Powered Version): Supports a wide voltage input range of 100V–240V, making it the efficient choice for fixed workstations and professional repair benches.
· MP305B (Built-in Lithium Battery Version): A truly milestone innovation. Featuring a built-in 70.56Wh lithium battery pack, it supports cordless operation in outdoor settings, completely eliminating the common pain point of having to hunt for a power outlet during field repairs or RC model debugging sessions.
II. Four Core Operating Modes for Comprehensive R&D Support
The MP305 is more than just a power supply; it is a consolidated suite of four professional tools:
1. High-Precision Programmable DC Power Supply (PPS)
Supports a continuously adjustable output range of 0–30V / 0–5A, with a maximum power output of 150W.
· Multi-Dimensional Monitoring: Features three built-in display modes—digital, analog (pointer), and waveform graph—to capture real-time current fluctuations.
· Automated Testing: Supports the storage of 10 programmable data sets, with each set capable of storing up to 100 distinct programming points. Engineers can utilize this feature to simulate battery discharge curves or voltage drop tests, thereby enabling automated burn-in testing.
2. USB-C PD Simulator and Fast Charging Testing
As a specialized tool for mobile device repair professionals, the MP305 features built-in, state-of-the-art PD (Power Delivery) protocols.
· Comprehensive Protocol Coverage: Supports PD 3.0, 3.1, and 3.2 standards.
· Intelligent Recognition: Capable of reading E-Mark chip information embedded in data cables, supporting power outputs of up to 140W. When repairing laptops or high-performance smartphones, it perfectly simulates the handshake process of an original charger.
3. Universal Battery Charger
Leveraging its linear output characteristics—which feature zero ripple—the MP305 can transform into an intelligent battery charging station.
· Wide Compatibility: Supports LiHv, LiPo, and Li-ion (1–6S); LiFe (1–8S); Pb (1–12S); and NiMH/NiCd (1–20S) battery types.
· Precise Temperature Control: Utilizes intelligent algorithms to monitor battery status, effectively preventing overcharging and overheating.

4. Cross-Platform Remote Interconnection System
This feature serves as the MP305's "killer app," setting it apart from traditional repair power supplies. It supports seamless connectivity across all major platforms: Windows, macOS, iOS, Android, and HarmonyOS.
· Wireless Control: Connect via Bluetooth to a mobile device to remotely adjust voltage and current settings directly from the screen, eliminating the need to repeatedly bend down to operate the unit.
· Waveform Recording: The PC application allows for long-term recording of current waveforms, enabling engineers to analyze power consumption fluctuations during standby, active operation, and sudden load spikes.
III. Product Craftsmanship and Cooling System
During prolonged periods of high-power output (e.g., at a full load of 150W), effective heat dissipation is the lifeline of any power supply.
· CNC-Machined Aluminum Alloy Body: The entire unit is crafted using a unibody CNC machining process, ensuring exceptional durability and rapid thermal conductivity.
· Variable-Speed Cooling System: Features a built-in high-RPM fan paired with intelligent temperature control algorithms; this system operates silently during low-power usage while rapidly dissipating heat during high-power operation.
· Expansion Mounting Points: The base is equipped with a 1/4-inch standard threaded hole, allowing for mounting on stands or brackets to facilitate convenient vertical desktop placement.
IV. Diverse Options for Varying Budgets
While the MP305 excels in terms of intelligence and linear output performance, the market offers other outstanding products worthy of comparison and consideration:
