T3PSX3200P Multi-Output Programmable Power Supplies

With the maximum output power of 217 W, Teledyne LeCroy's T3X3200P series, a multi-channel programmable DC power supply, includes four models: T3PS13206P (0 to 32 V/0 to 6 A) for single-channel output, T3PS23203P for dual-channel output (CH1: 0 to 32 V/0 to 3 A, CH2:0 to 32 V/0 to 3 A), T3PS33203P for three-channel output (Ch1: 0 to 32 V/0 to 3 A, CH2: 0 to 32 V/0 to 3 A, CH3: 1.8 V, 2.5 V, 3.3 V, 5.0 V/5 A), and T3PS43203P for four-channel output (CH1: 0 to 32 V/0 to 3 A, CH2: 0 to 32 V/0 to 3 A, CH3: 0 to 5 V/0 to 1 A, CH4: 0 to 15 V/0 to 1 A). This series not only provides high program resolution (1 mV/0.1 mA) and read back resolution (0.1 mV/0.1 mA) but also features optimal low-ripple noise characteristics ≤350 μV_RMS/≤2 mA_RMS and output transient recovery capability ≤50 μS. An independent output on-off switch is provided for each channel.

For series and parallel applications of CH1 and CH2, the tracking function of the T3X3200P series 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. However, excessively long, thin, or inconsistent external wiring may cause inaccurate voltage or current output.

The T3X3200P series offers a variety of display modes, including single or multi-channel setting values, measurement values, and waveform displays. The Monitor function of the T3X3200P series allows users to set monitoring conditions according to requirements, sound alarms or stop output during the measurement process, and stop the measurement and protect the customer's DUT.

The T3X3200P series 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 the PC for PC software or Excel to conduct future analysis. The CH1/CH2 of the T3X3200P series 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 batteries. Channel 1 and Channel 2 not only provide 32 V/3 A power output but also feature built-in maximum 32 V constant voltage (CV) load, maximum 3.2 A constant current (CC) load, and maximum 1 kΩ constant resistance (CR) load function.

The T3X3200P series 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 CV or CC load waveform, i.e., serial power output or a simulation test of a dynamic load. In order to simplify the setting of waveform editing, the T3X3200P series 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, Exp Fall waveforms.

The internal protection functions include OVP/OCP/OPP/OTP, in which the protection mechanism for OVP/OCP/OTP is implemented by a hardware circuit that has the advantage of faster response time compared with competitors who adopt software to achieve 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 the USB charging test.

The intelligent temperature-controlled fan can adjust the speed according to the temperature of the power transistor to reduce unnecessary noise. The output value setting and the Sequence/Delay/Recorder functions provide ten 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 T3X3200P series also has a LAN interface to facilitate different requirements. The commands of the T3X3200P series conform to SCPI requirements.
