RD6030W 60V 30A DC Voltage Current Step-down Stabilized Regulated Power Supply Module Buck Adjustable Converter Battery Charge

Good luck with your favorite purchasesNOTE about the noise about 1500W PSU: 1. There is a high-frequency noise when the switching power supply is unloaded, Due to the large output power range of the product, in order to reduce the power consumption of the switching power supply when no-load, the PWM control chip will jump some control cycles. Assume that the original working frequency is 60KHZ. If there are more skipping cycles, the working frequency will be reduced to less than 20KHZ. This Sometimes a noise audible to human ears is produced. The size of this noise is also related to the production process of the transformer. Since the winding and paint impregnation of each transformer's coil are slightly different, the noise of each product's operation is slightly different. 2. There is a loud sound when the fan is running; when the ambient temperature is high, the fan may work even if it is unloaded.

These are normal phenomena. It is recommended to turn off the AC switch when the product is not in use! If you mind it, please do not buy it. NOTE2: 1500W PSU is 1500W under 220V AC input, it can let RD6030 output 1440W max, but it is only 1200W under 110V AC input, it can only let RD6030 output 1140W max, please be careful when choosing PSU Parameter Model: RD6030-W Input voltage range: 7-70.00V Output voltage range: 0-60.00V Output current range: 0-30.00A Output power range: 0-1800W Input voltage measurement resolution: 0.01V Output voltage resolution: 0.01V Output current: 0.01A Battery voltage resolution: 0.01V Input voltage measurement accuracy: ±(1%+5 digits) Output voltage accuracy:±(0.3%+3digits) Output currentaccuracy:±(0.5%+5digits) Battery voltage measurement accuracy: ±(0.5%+3 digits) Default cutoff current value when charging: 100mA Output ripple typical: 50mV@15A, 90mV@30A VPP Working temperature range: -10℃~40℃ External sensor Temperature detection range:-10℃~100℃/0℉~200℉ External sensor Temperature detection accuracy:±3℃/±6℉ Constant voltage moderesponse time: 2ms（0.1A-5A Load） Constant voltage mode load regulation: ±(0.1%+2 digits) Constant current mode load regulation: ±(0.1%+3 digits) Capacity measurement range: 0-9999.99Ah Energy measurement range: 0-9999.99W Capacity and energy statistical error: ±2％ Buck working mode: （input voltage÷1.1）-1 Over temperature protection: System temperature>80℃ Screen brightness setting: 0-5(6 level in total) Screen: 2.4inch color HD display Weight(with package):About 0.74kg Product dimension: 167*81*69mm Cooling fan start condition: Output current>8A or System temperature>45℃ Cooling fan shut down condition:Output current <7.9A and System temperature <40℃
