DC/DC Converter, Model HZ-12-24 rel. 2

designed for two HZ-14 or two HZ-20 modules
size: 3.25 x 4.50 inches
weight: 5 oz.

Description

The HZ-12-24 DC/DC converter is designed to handle input voltages between 1.8 volts and 9 volts and output currents up to 2.5 amperes at voltages up to 15 volts. The output current at a particular output voltage depends upon the input voltage, and can be estimated from the input power, taking into account an efficiency of about 87%. The HZ-12-24 converter is well suited as a battery charger and provides a charging current proportional to the input voltage. An output voltage limiter is provided to prevent battery overcharging. The voltage limiting level is set by R19. The converter can also be used as a fixed output voltage device, by adjusting R19. The desired output voltage can, of course, only be obtained when input power and output load allows it.

Instructions for Use

At the input terminals apply the positive input voltage to input terminal 3 and the negative input to either input terminal 1 or 2. At the output terminals apply the positive side of the load to output terminal 2 and the negative side to output terminal 1. Polarities are marked on both input and output terminals. To adjust the output voltage limiter apply a light load, such as a 10 to 20 ohm resistor, to the output terminals. Connect a voltmeter to the output terminals and increase the input voltage until the output voltage is about 15 volts. Now adjust R19 such that the output voltage is the desired limiting value.
