TPM-series Programmable Switching DC Power Supply (90 ~ 375W)

TPM-series is single output programmable linear DC power supply with power ranging from 90W to 375W, voltage from 20V to 150V, and current from 1.2A to 10A. It offers multiple specifications of high-precision, cost-effectiveness and high performance. It features overload, reverse polarity, overvoltage, overcurrent and over temperature protection to ensure safe operation of the power supply and load in unstable environments. With a low regulation of 0.01% and low ripple and noise (less than 1mVrms), it automatically selects between continuous and dynamic loads, making it suitable for applications with current surges, high-precision desktop applications and test systems.

 Applications / Functions

  CC /CV function : This function allows the power supply to maintain uninterrupted operation during the transition from constant voltage mode to constant current mode as the load changes. The power supply has a timed output function, when enabled, the instrument will automatically switch the preset power supply to constant voltage/constant current operating mode.

 Timing output : The power supply has a timed output function. When activated, Instrument will output preset voltage and current values ​​to realistically simulate the operating conditions of various power supplies in reality.

  Remote sensing function : When the load consumes a large current, a voltage drop will occur on the connection line between the current and the load. Remote sensing can automatically compensate for the voltage drop of the load line.

 Battery Curved Charge : Instead of same charging voltage and current through out the whloe charging operation, a curved charge operation can perfeclty protect batteries under charge.

 Fast Response, high quality : With fast transient response time of 50µs. The output voltage can quickly recover to the set value when the load current changes instantanceously, thus ensuring output quality.

  Low Noise : Ripple : <1mVrms
