1.1 Product Overview and Features
The SM7860-01 to -07 and SM7860-21 to -27 are power supply units designed
for use with the Model SM7810 or SM7810-20 Super MΩ HiTester. They support
bipolar, multi-channel output and are compatible with multi-channel systems.
Used in combination with the Model SM7810 or SM7810-20 Super MΩ HiTester,
they are ideal for use in automated testing and measurement of capacitors.
Bipolar, multi-channel output
The device delivers an 8-channel, positive/negative power supply, allowing an
optimized testing line to be built using the smallest possible number of power
supplies.
Independent on/off output switching and current limitations
for all channels
Since each channel has its own output on/off switch, it is possible to control volt-
age application without an external circuit (allowing charging and discharging).
Use of semiconductor switches eliminates the need for maintenance. Addition-
ally, the ability to limit current (to 50 mA) for individual channels means the mea-
surement of other channels won't be affected when a target workpiece has a
short.
Output current capacity: 50 mA/channel
High-capacity capacitors can be charged rapidly, and the number of charges can
be reduced.
Output voltage: 1,000 V/channel
Devices are available with output voltages of up to ±1,000 V.
Standard interfaces
Devices ship standard with external I/O, GP-IB, and RS-232C interfaces for
sequencing. Interfaces are used to configure and power the devices.
