DN511
SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN511 is a subminiature proportionally controlled heater,
whose temperature can be programmed with a single external resistor.
A unique design allows this device to operate over a large voltage range
from 15volts to +60 Volts D.C. without drawing excessive current at
turn-on.Temperature of the DN511 can be set at the factory upon request.
The DN511 is in a ceramic package and can supply up to 3.5 watts of
power from an unregulated power supply.
FEATURES
• BERYLLIA BASE FOR GOOD THERMAL CONDUCTION
• REGULATION TEMPERATURE FROM 5°C ABOVE AMBIENT TO 100°C
• 15 TO 70 VOLT OPERATION
• ELECTRICALLY ISOLATED FROM THE CASE

The DN511 electrical
output pads are Pd-Pt-Ag
and can be soldered. The
solder used, such as SN-62,
should contain silver to
prevent leaching of the pads
from the substrate.
