Aprašymas

Uni-T UT658LOAD USB Tester

The Uni-T UT658LOAD is a USB tester designed to test chargers, power banks, USB Type-A cables, and other power supply devices. The device measures voltage, current, energy, capacitance, equivalent circuit resistance, and the voltages of the D+ and D- lines, allowing for a more accurate assessment of the operating parameters of the tested equipment. An additional advantage of this model is its built-in electrical load, which expands its range of applications during service, production, and hobbyist testing.

Wide measurement range and built-in load

The UT658LOAD model supports USB Type-A ports and 2.0 and 3.0 protocols, measuring voltage in the range of 4–24 V DC and current from 0.05 to 3 A DC. The device also allows monitoring of capacity up to 99,999 mAh, energy up to 1,000 Wh, equivalent circuit resistance from 1 to 480 Ω, and D+ and D- data line voltage in the range of 0–3.3 V. Built-in loads of 0.5 A, 1 A, 2 A, and 3 A with a maximum power of 60 W allow for more convenient testing of the behavior of power supplies and chargers under load.

Clear display and convenient data logging

The UT658LOAD displays the most important parameters simultaneously on a single screen, facilitating quick evaluation of results. The device supports 10 sets of data memory, a maximum recording time of 99 h 59 min 59 s, and the QC 3.0 fast charging protocol. With dimensions of 122 × 53 × 27 mm and a weight of 114.4 g, the model remains handy and convenient for everyday use.
