How to Enable Positive/Negative Output from DC Power Supply

How to Enable Positive/Negative Output from DC Power Supply

How to Enable Positive/Negative Output from DC Power Supply DC power supply can provide dual (positive and negative) output by following the method described in Section 1 below. 1. How to Produce Positive/Negative Output 1. Connect Power Supply 1 to Power Supply 2 in series. 2. Connect COM terminal to GND terminal. 3. Set each voltage from Power Supply 1 and 2. ...

PLZ Series: How to Effectively Improve Safety during Load Testing of Non-isolated AC/DC Converter

PLZ Series: How to Effectively Improve Safety during Load Testing of Non-isolated AC/DC Converter Considering minimising the potential shock hazard, the use of an isolation transformer or regulated power supply is critical during load testing of a non-isolated AC/DC converter (such as PFC). This white paper explains; what happens without an isolation transformer or regulated A...

How to Calculate Input Current for PCR-LE/MA Series

How to Calculate Input Current for PCR-LE/MA Series Before installing PCR-LE or MA Series, you may want to know how much current should be supplied from the distribution board. The best way is to calculate the current consumption (= input current) of your PCR-LE or MA Series. Here are the examples how to calculate the input current based on your output requirement (your outp...

Parallel Operation with Different Power Supply Models

Parallel Operation with Different Power Supply Models The same model of Kikusui DC power supplies can be connected in parallel. By connecting the signal cables, one unit is set as the master unit and it can control the other units. This operation is called as ‘master-slave parallel operation’. Master-slave parallel operation is not available when connecting the different ...

CC-CV Charging System without Series Diode

CC-CV Charging System without Series Diode To charge batteries, it is recommended that you connect a diode in series at an output of DC power supply (See Figure 1). With a diode, constant current (CC) can be properly supplied; however constant voltage (CV) may be unstable if using remote sensing at battery terminals. Without a diode, a high c...

How to Enable Positive/Negative Output from DC Power Supply

Programming Example: SSA/SVA analyser screen image capture using Python over LAN

Here is a brief code example written in Python 3.4 that uses a socket to pull a display image (screenshot) from a SIGLENT SSA/SVA analyser via LAN and save it to the local drive of the controlling computer. NOTE: This program saves the picture/display image file in the same directory that the .py file is being run from. It will overwrite any existing file that has the same na...

Build FM NRSC masks for SIGLENT SSA3000X/SVA1000Xs using a Python script

Many broadcast applications require monitoring a transmitter and observing the output amplitude vs. frequency. For FM radio applications, a common mask is defined by the National Radio Systems Committee (NRSC) and is commonly referred to as the FM NRSC mask. A very helpful SIGLENT owner, Dan from Alabama Broadcast Servi...

Testing Intrinsic Safety Barrier fusing and circuitry using an Electronic Load

From Wikipedia: Intrinsic safety (IS) is a protection technique for safe operation of electrical equipment in hazardous areas by limiting the energy, electrical and thermal, available for ignition. The idea is to minimise the risk of fire or explosion by physically eliminating any potential source of ignition. Many IS circuits utilise special fusing and elements that are de...

Programming Example: Controlling an SPD power supply via Sockets over LAN

Here is a Python 3.6 example of using sockets to control an SPD power supply connected to a computer using LAN. NOTE: The SPD uses VXI-11 protocol for LAN. On some systems, it is helpful to use the VXI-11 format for the IP address: “TCPIP::ip.add.re.ss::INSTR” Here is the program in full: ...
