YIHUA 3005D Adjustable Laboratory DC Power Supply programmable

150W YIHUA 3005D Digital Program Controlled Switching DC Power Supply, 5A 30V Adjustable Laboratory DC Power Supply Digital Program-Controlled.Specification:Model: 3005DOutput Power: 150WPower Supply Voltage: 220V ±10% 50Hz or 110V ±10% 60HzExport voltage: Continuously adjustable from 0 to 30VVoltage export accuracy: ±0.05VRecovery time: 100uSConstant current value: 0~5A Accuracy: ±0. 01AConstant output current: Continuously adjustable from 0 to 5AOCP current value: 0-5A Accuracy: ±0. 01ASignal test frequency range: 30~1800MHz (including cell phone signal test)Signal strength: 10dBMFeatures:1. Digital program-controlled stabilized switching power supply is designed for use in laboratories, schools, production lines, and electronic repair.2. Small size and lightweight, which is very easy to transport and carry.3. High voltage stability, small ripple factor, excellent short circuit protection, and over-current protection. High efficiency, high load capacity, and low noise and is superior to linear power supplies.4. Digitally adjusts current and voltage, which is more advanced, more stable, and has longer life than traditional potentiometer adjusters.5. Output electronic protector switch, which can easily break the output load. Function set lock that can effectively prevent change of output parameters or change caused by misuse, which makes the product more secure and reliable.6. Mobile phone radio-frequency detection function, which is of a 4.2V 2A/19V 5A fixed output function. Parameters can be displayed by pressing the key, which is fast and convenient. It is an essential tool for cell phone and laptop repair.7. Three storage memories that can store three sets of frequently used parameters for easy retrieval.8. Output state memory function. When the memory switch is turned on,it can retain the output status before the power switch is turned off. For example, when the power is in the output state, turn off the power switch, and when the power switch is turned on the next time the power supply will directly output the voltage. When the memory switch is turned off, it will not retain the output state when the power switch is turned off. Every time the power switch is turned on, the output key must be pressed to output voltage.
