WBK61 and WBK62 High-Voltage Adapters
Description
The WBK61 and WBK62 are single-channel high-voltage adapters that can be used with WaveBooks, or
with WBK10A expansion modules. In addition, WBK61 and WBK62 can be used with WBK11A,
WBK12A and WBK13A signal conditioning cards.
WBK61 and WBK62, Product Comparison
WBK61 WBK62
Voltage Divider 200:1 fixed 20:1 fixed
Maximum Voltage 1000 Vpeak (on either input reference to
earth ground) 100 Vpeak (on either input reference to
earth ground)
Maximum Differential
Voltage 2000 Vpeak (if neither input exceeds
1000 Vp rating to earth ground) 200 Vpeak (if neither input exceeds
100 Vp rating to earth ground)
The channel output connection [for both the WBK61 and WBK62 voltage adapters] is made through a
BNC-to-BNC coupler. Each model has two signal input-connections, one for low-signal input, and the other
for high-signal input. The input channels are resistively isolated from ground, providing for safe connection
of the test device. Series resistors, for both high and low channels, serve as attenuators and provide a
maximum current limit of 100 µA.
The WBK61 and WBK62 include:
•
Input HI, safety-style banana-jack
•
Input LO, safety-style banana-jack
•
60-inch (152 cm) cables with probe tips and alligator clips
•
Green stacking banana plug (for analog common)
•
CN-110 BNC-to-BNC Coupler
•
CN-111 Banana Plug/Alligator-clip earth-ground cable
The following figure provides a simplified schematic for each model.
WBK61 and WBK62 Schematics
Note 1: Channel input connections are made from the WBK61/62 BNC to a Channel BNC on the WaveBook data
acquisition system or to the WBK10A analog expansion module. A CN-110 BNC-to-BNC Coupler is used to
make the connection. Refer to the
Hardware Setup section of this document module for information regarding
channel and ground connections.
Note 2: The variable resistors are factory set at 50 K Ω and are not user-adjustable.
