The Teledyne LeCroy T3PS33203P Triple-Output Programmable Linear DC Power Supply features an independent output on-off switch for each channel. For series and parallel applications of CH1 and CH2, its tracking function utilizes the internal circuit to automatically switch the output to serial or parallel output without additional external wiring, providing users with convenience not only in operating procedures, but also a more stable output. The tracking function design of other brands requires additional external wiring connections for the output in series or parallel.

The T3PS33203P offers a variety of display modes, including single or multi-channel setting values, measurement values, and waveform displays. The Monitor function allows users to set monitoring conditions according to requirements, sound alarms or stop output during the measurement process, and stop measurement to protect the customer's DUT. It provides output recorder function, which records the voltage/current of the output process to the internal memory, and the result can be stored as a (*.REC) or (*.CSV) file, which can then be transferred to the USB flash drive and be exported to a PC for future analysis.

The T3PS33203P's CH1/CH2 are designed with the load function. A single power supply can set one channel as the power output, and one channel for the load function to consume the power of the DUT to meet the basic charging and discharging test requirements for a battery.

The T3PS33203P provides the sequential output function on Channel 1 and Channel 2. This function not only allows users to edit the power output waveform, but also allows users to set the sequential constant voltage (CV) or constant current (CC) load waveform (i.e. a serial power output or a simulation test of a dynamic load). In order to simplify the setting of waveform editing, it has eight built-in template waveforms in the sequence output function for users to directly apply for output, including Sine, Pulse, Ramp, Stair Up, Stair Dn, Stair UpDn, Exp Rise, and Exp Fall waveforms.

The internal protection functions include OVP/OCP/OPP/ OTP, in which the protection mechanism for OVP/OCP/ OTP is implemented by hardware circuit. This has the advantage of faster response times compared to power supplies that adopt software to achieve certain protections.

The OVP/OCP functions allow users to set the protection action point (except CH3 of T3PS33203P) according to the conditions of the DUT. The OPP is only activated during the operation of the load function. The Delay Function sets the length of time during channel 1 or channel 2 power output on or during power output off.

In addition, the Trigger In/Trigger Out functions synchronize external devices. The T3PS33203P channel 3 adds a 3 A USB (Type A) output terminal for USB charging test. The intelligent temperature controlled fan can adjust the speed according to the temperature of the power transistor so as to reduce unnecessary noise. The output value setting and the Sequence/Delay/Recorder functions provide 10 sets of internal memory for use, and can be loaded/stored using a USB flash drive. In addition to the standard RS-232 and USB remote interfaces, the T3PS33203P has an LAN interface to facilitate different requirements. All commands conform to SCPI requirements.
