DUT Power Supplies

DUT Power Supplies

Figure 3-9    DUT power supplies


The rows in the DUT power supplies table correspond to the power supply relays on the ASRU card. Define the configuration as follows:

  • Custom power configurations:
    If the target test system does not have standard power supply configurations, specify all the parameters in each row. Table 3-3 describes the parameters.
  • Standard power configurations:
    If the target test system has standard configurations, simply select the power supply type in the PS Type column. The parameters for the selected type will automatically be filled in.
For information on supported power supply configurations, scroll down to the bottom of the screen. Click the button for a power supply type to see its specifications. The specification are also given in Table 3-6.

 
Power supply configurations must match the hardware installed in the testhead. The power supply connections and types are not configurable via the software. The power supplies are hard wired to resources in the system.

Also note the following:

  • The old power supplies (66xx) cannot be used together with the newer power supplies (N67xx).
  • Existing test programs set up for 6634 power supplies will run without modification on systems with N6746 power supplies.
  • Existing test programs set up for 6621A power supplies will run without modification on systems with N6752 power supplies.
  • Existing test programs set up for 6642 power supplies will run without modification on systems with N6773 power supplies.

Table 3-3    Custom Power Configurations

Column
Description
PS Type
Power supply type (model).1
PS Num
Power supply number. Note that the power supply numbers are different for each module (see Table 3-4). It is recommended that the power supply numbers should match the actual testhead wiring.
Output
The output used on the power supply (Table 3-5).
ASRU Channel
The channel to which the power supply is wired.
Note that each relay can carry a maximum of 5A so it is necessary to wire high current outputs to two ASRU channels using the same power supply number and power supply output.

1   When PS Type ps6752 is selected, the power supply number, output, and ASRU channel are automatically assigned and cannot be changed.

Perhitungan & Cara Merubah Kumparan Blender Dari 220 V Menjadi 12 V

          Seperti yang telah dijelaskan pada buku “menggulung motor listrik arus bolak-balik, servis peralatan listrik rumah tangga kelompok penggerak dan perbaikan peralatan listrik pertukangan”, bahwa motor penggerak yang digunakan pada perlatan listrik rumah tangga dan pertukangan seperti blender, mixer, bor tembak, gerinda dsb menggunakan jenis motor universal. Motor universal adalah jenis motor listrik yang dapat disuplai dengan sumber listrik arus bolak-balik (AC) dan arus searah (DC). Jadi peralatan-peralatan listrik rumah tangga dan pertukangan tersebut yang biasanya kita suplai dengan sumber listrik AC dari PLN atau Genset sebesar 220 V sebenarnya dapat juga kita suplai dengan sumber listrik DC yang tentunya tegangan juga harus sama yakni 220 V.           Yang menjadi permasalahan bagaimana kalau peralatan listrik rumah tangga atau pertukangan tersebut, sebagai contoh misalkan blender yang ingin digunakan atau dioper...

Testhead

4.3         Testhead The testhead is that portion of the tester that supports the PIN, ASRU and Controller cards.   The testhead is divided into two BANKS and each BANK is divided into two MODULES, see figure 2 below.  Bank 1 contains modules 0 and 1, bank 2 contains modules 2 and 3.  The test fixtures are placed on the banks of the tester and locked down for board testing.  The testhead cards interface to the test fixture through the spring loaded pogo pin “nails” at the top edge on each of these card types. 4.4       Support Bay The support bay is a stand-alone cabinet that houses the power supplies for the Unit Under Test.  This bay also houses the test station power distribution unit and test station controller on earlier models. 4.5       Emergency Shutdown Switch The emergency shutdown switch is the large red button located at the lower left corne...

Kelebihan dan Kekurangan Saluran Listrik Jenis Saluran Udara dan Saluran Bawah Tanah

Berdasarkan pemasangannya,   saluran distribusi dibagi menjadi dua kategori, yaitu : saluran udara (overhead line) merupakan sistem penyaluran tenaga listrik melalui kawat penghantar yang ditompang pada tiang listrik. Sedangkan saluran bawah tanah (underground cable) merupakan sistem penyaluran tenaga listrik melalui kabel-kabel yang ditanamkan di dalam tanah. 1.    Saluran Bawah Tanah (Underground Lines) Saluran distribusi yang menyalurkan energi listrik melalui kabel yang ditanam didalam tanah. Kategori saluran distribusi seperti ini adalah yang favorite untuk pemasangan di dalam kota, karena berada didalam tanah, maka tidak mengganggu keindahan kota dan juga tidak mudah terjadi gangguan akibat kondisi cuaca atau kondisi alam. Namun juga memilik kekurangan, yaitu mahalnya biaya investasi dan sulitnya menentukan titik gangguan dan perbaikannya. Kedua cara penyaluran memiliki keuntungan dan kerugian masing-masing. Keuntungan yang dapat diperoleh dari suatu jaringan bawah...
