Dual DC power supply wholesale Shenzhen I. Overview MCH-300 dual power series, power supply is an adjustable multi-function and high stability DC power supply. Be continuous full load output, the output voltage and current in the standard range continuously adjustable. DC power supply than is generally difficult to achieve the high stability, strong reliability and durability of the power supply, scientific research departments, universities and enterprises that require high stability of the DC power supply ideal . Second, the specification Model Voltage 0 ~ 30V fixed output current 5V / 2A dual output 0 ~ 2A 0 ~ 3A 0 ~ 5A MCH-302D-II ● ● ● ● MCH-303D-II ● ● ● ● MCH-305D-II ● ● ● ● Input voltage: 110V / 220VAC ± 10% 60 / 50Hz (when ordering) Rated output power: 60W X 2 = 120w (2A) 90W X 2 = 180w (3A) 150W X 2 = 300w (5A) Operating Environment : Temperature: 0 ℃ -40 ℃ Humidity: ≤90% RH preservation of the environment: Temperature: 20 ℃ -80 ℃ Humidity: ≤80% RH 2 Third, the technical indicators Model MCH-302D-II MCH-303D-II MCH-305D- II Variable Output: Output voltage: 0 ~ 30V continuously adjustable output current continuously adjustable from 0 to nominal value source effect: ≤lx 10-4 + 3mV load effect: ≤1 x 10-4 + 3mV Ripple Noise: ≤ 1mV (rms) 4 groups of three figures display error ≤ 0.5% + ld fixed output voltage of 5V 2A output current output source effect: ≤5mV load effect: ≤15mV ripple noise: ≤2mV (RMS) Other: Enter Power: 110V / 220V ± 10% 60 / 50Hz (when ordering) Dimensions 260 x 165 x 300 (mm) Weight (kg) of about 7.2kg to about 8.6kg to about 11kg 3 four panel functions and operating instructions 4.1 panel features: (1) power switch. (2) Independent / serial / parallel control keys. When you select a series mode, two-way power supply is connected in series. A voltage channel by channel B control. Then you can get one pair of opposite polarity voltage. Connected to the negative and positive channel B Channel A can get double the voltage output. When you select the parallel mode, and two-way power is connected, then at any one output terminal 4 can get double the current. (3) three voltage / current value is displayed (4) three voltage / current value is displayed. (5) C.C constant current indicator. (6) C.V constant pressure indicator. Note: When the load current (calculated according to Ohm's law) is lower than the preset current values, CV lights, then the power supply operates in constant voltage mode. Conversely, CC lights when the power in the constant current mode, is limited by the pre-load supply current value. (7) Voltage coarse / fine adjustment. (8) voltage coarse / fine adjustment. Note: If the series or parallel state, the knob for channel A does not work. (9) The current coarse / fine tune. (10) The current coarse / fine tune. (11) the output of a fixed 5V / 2A output. (12) output 2, by (7) and (9) keys. (13) an output terminal 3, from (8) and (10) keys. 5 4.2: 1 port connection: the output terminal 12 and the output terminal 13 is floating shape. Fixed output and the negative terminal 11 has internal ground. 2. Voltage setting: adjust the voltage knob to get the required voltage. 3. The current setting: counterclockwise rotation adjustment voltage control, a smaller voltage value obtained. Shorting the output, adjust the current knob to the desired setting of the current value. 4. tandem: by selecting the button 2-line mode (while bouncing on both sides independently, left press line mode, the left and right while pressing for parallel mode) "+" terminal and the output terminal 12 with output of 13 The "-" terminal as an output. In this case the output voltage of the power supply voltage is the sum of two-way. 5. parallel: The parallel mode selection button 2, the use of any way the power of the output, then the output current is the sum of the current two-way power supply.
