Functions
Four-quadrant Output Range
High voltage amplifier is generally equipped with the "sink" function for output currents that provides constant voltage operation without regard to the type of load whether it is capacitive or conductive.
As it gives fast response, it is an ideal power supply for applications which require AC output. Matsusada Precision high voltage amplifiers are all bipolar type and can be operated in full four-quadrant area. (I, · II, · III, · IV, and area)
Specifications
Options
- -LCs
-
Overcurrent value setting function
The overcurrent value is set by external voltage +0.5 V to +10.5 V. When this option is chosen, please be sure to output, where external voltage is impressed to AMJ.
BNC terminal is supplied on the front panel.
- -LN
-
No power failure protection
The output can be turned ON/OFF linked with the input voltage.
- -L1
-
Output current monitor
Output voltage: -10 V to +10 V from BNC terminal on the front panel
The Output impedance is 1 kΩ up to 2 kHz of bandwidth.
- -L(5m)
-
Changing the output cable length to be 5 meters
Change the length of the High-voltage output non-shielded cable standard 1.5 meters to 5 meters.
-LCs, -L1 options can be chosen only one either. Selecting multiple options is unavailable at the same time.
