A362 Battery Charger
Сatalog number:
SYS-A382
BATTERY CHARGER
An innovative three-step charger, A382 employs fast, medium, and trickle charges at a safe, low current, greatly extending battery life. After a fast initial phase, the charger automatically switches to a constant voltage mode. When charging is complete, the charger switches to the trickle-charge mode. LED lamps indicate charging status. (For use only in charging batteries installed in the A385.)

Dummy Load Resistor Kit
A365 can be used as a precise voltage source by placing a precision “dummy” resistor load across the output terminals. Precision resistors (such as the 100 Ω, 1000 Ω and 10,000 Ω resistors in WPI’s optional Dummy Load Resistor Kit #DRL) when placed across the output terminals convert the precision current levels to accurate voltage levels.
For example, 1 milliampere flowing through 1000 Ohms will produce 1 volt across the output terminal pair. Thus, models A365D and A365R can be used as low noise sources of accurate voltage pulses or DC. To maintain less than 1% error, avoid shunting the output dummy resistor with a load resistance less than 100 times the dummy resistance value.
High Current Stimulus Isolator
The A385 is an optically isolated current source, which can generate up to 100 mA of unipolar or biphasic constant current pulses or DC. Pulse duration is controlled manually or by an external 5V command. Output current amplitude is determined by a 3-digit 10-turn potentiometer. Maximum output voltage between the stimulating electrodes is +36V.
Linear Stimulus Isolator
Model A395 generates a user-defined output current of wave shape; DC, AC, pulse and combinations. Battery operated, photoelectrically-isolated from the input voltage drive, the instrument regenerates output currents which are linearly proportional to the analog voltage waveforms provided by your D/A converter or signal generator.
Single Channel Pulse Generator
The A310 pulse generator/stimulator combines the reproducibility and accuracy of digital electronics with the fine resolution and continuous adjustment possible with analog circuitry. All timing parameters are entered with high resolution, ten-turn potentiometers and six-position range switches. Timing is accurate to within 1% of the set value.
