1、 Product introduction
PS-18 portable DC power supply is a general power supply equipment for power system relay protection, high-voltage equipment test equipment and circuit test. The test power supply takes advanced PWM switching power supply technology as the core, adopts precise multi turn potentiometer adjustment, LED LCD display, wide voltage adjustment range, high voltage stabilization accuracy, and strong resistance to current impact. The power supply also integrates a three channel intelligent millisecond meter function. The millisecond meter can be started by the power supply output signal or the external switch input signal, and can simultaneously time the three external switch input signals. Because the function of the millisecond meter of this product is realized by using a single chip computer, the timing accuracy of the millisecond meter and the degree of intelligence in use are greatly improved.
2、 Main features
● Small size and light weight, with length and width area smaller than A4 paper area.
● It integrates two functions of general adjustable power supply and three channel intelligent millisecond meter;
● DC10V~260V wide range voltage output, precision constant voltage and constant current power supply;
● Precise multi turn potentiometer adjustment, with continuously adjustable output voltage;
● 10A output can work for a long time, and can be used for DC screen or battery charging.
● LED large screen display, which can display the set voltage, current value and the actual output voltage and current value;
● Complete over-current, over-voltage, short circuit, overload and overheat protection with high reliability;
● The millisecond meter can be started with power output or by external switching value;
● The on/off time and on/off state of external switching value can be measured simultaneously;
● Each switching value can save eight groups of time data.
