Designed to meet the needs of lower-voltage, higher-speed, e gg,gp, g d o e t n ed o o e o a g r e d and multi-channel testing applications n m t h n t p a o > The current trend in semiconductors is towards lower voltages and higher speeds. This trend places similar demands on both the components of semiconductor power units, such as switching power supplies, batteries and DC/DC converters, and also on the electronic loads used for testing. Also, a growing number of users with a need for multiple-output power units and easy channel reconfiguration are calling for plug-in type electronic...

The electronic load system is as wide as a 19-inch rack with a height of 3U. Weighing about 11 kg when confi gured for three channels or about 17 kg when confi gured for fi ve channels, the system is compact, lightweight and space-saving. The PLZ70UA model operates even when the input operating voltage is 0 V. This feature is indispensable for testing single-cell fuel cells. The continuing trend toward lower power consumption and semiconductor process miniaturization is driving semiconductor devices to operate with increasingly lower voltages. This makes PLZ70UA suitable for use when...

1 > Front-panel load input terminals 9 > Unit indicators V RANGE: In the CV, CC+CV or CR+CV mode, each time you press this key while holding down the SHIFT key, the range toggles between L and H. These terminals are used to connect this system to the device to be tested. Identical sets of load input terminals are provided on the front and rear panels, and are connected in parallel inside the system. The LED indicates the unit of the measurement value. 16 > SET key 10 > SW/SEQ/EXT/ALM lamps This key is used to select whether the current, resistance or voltage value to be set. In the CC+CV or...

1 > Rear-panel load input terminals 4 > AC INPUT 8 > CH CONT These terminals are used to connect this system with the device to be tested. They are connected to the load input terminals on the front panel in parallel inside the system. This connector is used to perform load on/off and external voltage reference control from the outside. It is also equipped with the terminals for current monitor output and power supply output for control. 5 > GPIB 2 > Rear-panel remote sensing terminals Sensing lines are connected to these terminals when compensating for voltage drops due to load wire...

Parallel operated load modules are regarded as a single channel, and their total current and resistance (conductance) values are used as displayed and set values. Parallel operated load modules and standalone load modules can coexist in the same frame. * PLZ-50F can accommodate up to fi ve load modules.When PLZ-50F houses one set of three parallel operated load modules and another set...

The soft start function allows the rise time of the current to be changed after the load-on operation in constant current mode. Since the rise time for the system can be changed according to the output-voltage rise time for the device being tested, you can conduct tests under highly realistic load conditions. (The soft start time can be selected from the following options - 0.1, 1, 3, 5, 10, 30, 100 and 300 ms.) This function configures the settings related to the system operation, communication environment, etc. These settings are stored in the system memory and called when the power is...
