Brief Introduction SPD3303C LED series Programmable DC Power Supply is convenient, flexible and multi-function. It is designed with three groups of independent output terminals, the output voltage of two groups is adjustable and another group is fixed to select: 2.5V, 3.3V, and 5V. The instrument also provides output short circuit and overload protection. Main Features Three independent output channels, two of which are controllable, with a total power up to 195W; Compatible design for power voltage: 100V, 110V, 220V and 230V to satisfy different power network; Capable of saving and recalling...

Chapter 1 Quick Guide In this chapter, we mainly introduce the panel and display of SPD3303C, as well as the new machine inspection and attentions at first use. Reading the following steps will give you a quick understanding on operation. General Inspection 1. Inspect the shipping container. Keep the damaged shipping container or cushioning material until the contents of the shipment have been completely checked and the instrument has passed both electrical and mechanical tests. The consigner or carrier will be responsible for damages to the instrument resulting from shipment. SIGLENT would not...

Safety Considerations To ensure that the instrument can work normally, please conduct necessary inspection before using the SPD3303C. Input Power Requirement The SPD3303C allows a 50Hz/60Hz frequency, and four levels of AC power: 100V/120V/220V/230V. You can select wanted power voltage with the “DIP Switch ” at the rear panel according to the actual demand. Warning To switch to the wanted power voltage, please disconnect the power cord first. Electrical Check Please use the power cord provided as accessory and connects the instrument to AC power. Check the power as the following steps. 1. Connect...

Output Checking To make sure the instrument can correctly respond to operation from the front panel, please perform the output checking, which includes voltage checking when all channels are with no load and current checking when short circuit occurs. 1. Output voltage checking (1) With the instrument no load, turn on the power, and make sure the current value displaying is not zero; (2) Check the output voltage of CH1/CH2 Turn on CH1/CH2 channel and the instrument acquiescently works in CV mode. Check whether the voltage value is adjustable from 0V to 32V. 2. Current output check (1) Turn on...
