ST4073 Introduction • Floating DC supply voltages • DC : 0 - 30V; 0-2 Amp • Constant voltage & constant current operation • Digital display for voltage and current • Adjustable current limiter The ST4073 30V, 2A Power Supply has been designed as a constant current (CC) and constant voltage (CV) source for laboratories, industries and field testing applications, featuring low power loss, compact and light weight.
ST4073 Technical Specifications DC Output : 0-30V, continuously variable by means of coarse and fine controls Output Current : 2A (Maximum) Setting Resolution : Voltage : 10mV Current : 5mA Internal Resistance : ≤ 10 mΩ Stability : ≤ 2.5 mV at 30V/2A Recovery Time : ≤ 50 µs Load Regulation : ≤ (0.05% + 10 mV) Line Regulation : ≤ (0.05% +10 mV) Temperature Coefficient : ≤ (0.
ST4073 Front Panel Control 1 Power : Push switch for supplying power to instrument. 2 V/A (Push button) : For switching the display from voltage to current reading or vice versa. When the pushbutton is pressed, the current supplied from the terminals (5) is displayed with a resolution of 10mA. In released position the voltage across the terminals (5) is displayed with a resolution of 0.1 V. 3 Coarse : (adjusting knob): For the coarse setting of the output voltages. 4 I Max.
ST4073 Operating Instructions General Information : The logical front panel layout of 30V- 2A Power Supply makes it easy to become familiar with the operation of the instruments. However, even experienced users should read the following instructions thoroughly before using the instrument. After unpacking the instrument, check for any mechanical damage or loose parts inside. Should there be any transportation damage, inform the supplier immediately and do not put the instrument into operation.
ST4073 First Time Operation : After unpacking the instrument check for any mechanical damages. The instrument should be plugged in mains-plug of proper mains supply 230V ± 10%. Switch ‘On’ the instrument, the power ‘On’ is indicated by lighting of displays. Operation : The Power Supply has an electrically floating output. This permits easy series connection with other Power Supply units, to increase supply voltage or current respectively.
ST4073 Functional Checks The 30V- 2A Power Supply should regularly be tested to assure proper functioning. The following test checks out the power supplies performance and suggestions for adjusting specific values. The adjustment will only be meaningful if the below indicated or equivalent instruments are used. Prior to the functional test or adjustment, the instrument should be on for at least 30 minutes. Measuring Instruments required : 1. 4 ½ Digit DMM; 4011 Handheld or equivalent 2.
