3B Scientific 1017781 Charge and Discharge Apparatus 230V

Charger and Discharger (230 V, 50/60 Hz). Compact equipment for recording charging and discharging curves for capacitors at individual points. Includes 12 V AC plug-in power supply. The charger and discharger consists of three units in a single housing: a voltage comparator, a digital counter and three resistor-capacitor pairs. The comparator compares the charging and discharging voltages with a set comparison voltage, which can be selected from any of 11 values between 0 to 10 V. The digital counter indicates the charging and discharging times for the capacitor as soon as the set comparison voltage is attained. In addition there are pairs of sockets for connecting an external resistor and an external capacitor.

Features:

• Internal capacitor: 2067 nF
• Internal resistors: 2.2 kOhms, 5.1 kOhms, 10 kOhms
• Digital counter: 4-digit, quartz controlLed
• Maximum value: 200 s
• Resolution: 100 ms
