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.

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.

The temperature of the DN511 is supplied with
four 3 inch #32 gage magnet wire as shown
below. Temperature of the DN511 can be set at
the factory on request
3.0" ± 0.25"
20.0
It is recommended that the DN511 heater be
attached to the device being heated with a
thermally conductive adhesive such as Loctite®
384. This will insure that there is minimum
thermal resistance between the two surfaces.
