SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN515 is a subminiature proportionally controlled heater whose
temperature can be programmed with a single external resistor. This device is
ideally suited for regulating the temperature of sensitive electronic components
such as microwave filters and crystal oscillators. The DN515 is in a ceramic
package and can supply up to 28 watts of power from an unregulated 28 Volt
power supply.
