The Instek PSB-2800L Programmable, Multi-range output DC power supply, which is a high power density, programmable and multi-range output DC power supply. The Instek PSB-2800L has the output voltage of 0~80V, and the output power ranges of 0~800W. The multi-range output functionality facilitates flexible collocations of higher voltage and larger current under the rated power range. Both series and parallel connections can be applied to the Instek PSB 2800L to fulfill the requirements of higher power output range.

The Instek PSB2800L provides three sets of preset function keys to memorize regularly used settings of voltage, current and power that users can recall rapidly. The sequence function, via RS232C, USB interface or optional GPIB interface, can connect with the computer to produce output power defined by sequence of a series of set voltage and current steps that are defined by the computer. This function is often used to establish a standard test procedure for the verification of the influence on DUTs done by the swiftly changing operating conditions.

The Instek PSB-2800L protects over voltage and over current. The power supply output function will be shut down to protect DUTs while the protection mechanism is triggered to function. When conducting battery charging operation, the Hi-W mode of the Instek PSB-2800L will prevent reverse current from damaging power supply. The Instek PSB-2800L provides analog control and analog monitor interfaces on the rear panel to control Instek PSB-2800L output via the external voltage or to externally monitor voltage and current output status of power supply. The Instek PSB-2800L's panel can be rotated 90 degree angle suitable for vertical or horizontal position to accommodate the ideal space utilization.

Multi-Range Output

Compared with the maximum power output of the conventional power supply that is calculated by the maximum output voltage muliples by the maximum output current, the Instek PSB-2800, defying the formula, has a unique characteristic of multirange output (Voltage and current). This distinguishing feature, under the same maximum power output range, can output a higher voltage with a smaller current and vice versa. For instance, for a conventional power supply with a maximum power output of 360W, the maximum voltage and current outputs are likely to be 10V and 36A respectively. Comparatively, Instek PSB-2800L, with the maximum breaking the limitation of Pmax=Vmax x Imax, broadens voltage and current application ranges, The following diagrams illustrate the voltage and curent comparison between the multi-range output power supply and the conventional power supply.

Series & Parallel Connections

Hence, the Instek PSB/2800L, with its multi-range output function and the power extension capability of the series and parallel connections, is the high power density and high performance to cost ratio DC power supply, which provides a wider range of power aplications for any limited equipment space. The Instek PSB-2800L is an ideal selection for testing DC power supply module, automobile lithium and lithium iron battery and electronic parts.

Preset Function

The Instek PSB-2800L provides three sets of parameter preset function keys on the front panel and each parameter preset memory includes output voltage, output current, and output power. Users can speedily recall frequency used settings through operating the front panel preset keys to store everyday settings.

OVP and OCP Functions

OVP & OCP Functions

OVP & OCP Functions

When the voltage and current output exceed the preset conditions, the Instek PSB-2800L will shutdown the output function to prevent DUTs from damaging. The OVP and OCP protection level can be set to 10% ~ 110% of the rated voltage or current and the preset condition is 110% of the rated voltage and current.

Sequence Function

When applying sequence functions, the computer must first edit a series of steps defined by different voltage, current, and duration. These steps are then sent to the Instek PSB-2800L's memory, in CSV format, via RS-232C, USB interface or GPIB interface (optional) to periodically produce a series of steps defined by a different voltage, current, and duration. The minimum for each sequence is set to one second and the maximum number of step is 100. This function is to test the impact of DUTs done by the rapidly changing power supply. The reliability test of electronics products toward changing power supply is one of the very important verification items.

90 Degree Angle Rotatable Control Panel

Taking working space utilization into consideration, the Instek PSB-2800L can be placed vertically or horizontally by its unique design of 90 degree angle rotatable control panel for users' ease-of-use.

External Control & Analog Monitoring Function

The rear panel of the Instek PSB-2800L provides 26pin analog control connector and users can control output voltage and current value via external voltage or resistance. Furthermore, the Instek PSB-2800L power supply's output on and off or AC input shut down can also be executed through the external control connector. The designated pin of the port can be measured to monitor output voltage and current. The following diagrams illustrate several typical external control application connections.

  • 1 - User Manual (CD)
  • 1 - AC Power Cord
  • 1 - External Control Connector (26-pin)
  • 1 - Screws for output terminals on rear panel
  • 1 - Protection covers for output terminals on rear panel
  • 1 - Protection caps for output terminals on the front panel
  • 1 - GND Cable
