The HM169 circuit is connected to the mains electrical
supply and operates at voltages which need to be
protected by proper enclosure and protective covering.
While it has been designed to conform to relevant
Australian and overseas Standards (such as AS3300 and
AS3313), it should only be used in a manner that ensures
the appliance in which they are used complies with all
relevant safety and other requirements.
The board must be mounted with non-conductive clips,
and positioned such that the minimum creepage distances
from the circuit assembly to earth, and between high
voltage points is not transgressed.
The NTC element is electrically live and connected to the
mains, and must therefore be electrically insulated. Also
creepage distances must be maintained for all live parts in
the circuit and its wiring, especially with respect to the NTC
thermistor.

Limiting values in accordance with the Absolute Maximum System (IEC 134).
Note
1. The operating voltage range can be set to any desired ac range by selection of power supply resistors. Application
2. The HM169 heatsink will permit load currents of up to 6 Amps if it is mounted with a reasonably free flow of air across

the heatsink surface. Load currents up to 10 Amps may be used with additional heat dissipating capability, together
with temperature measurement in situ to demonstrate that under worst case ambient temperatures the triac junction
temperature remains within its published ratings. These current ratings are suited to the triac commonly used in
samples, the BT139X-600E, other loads may be better suited to design with another triac which will require different
peak current ratings.

CONDITIONS

It should be noted that there are Mains Voltages on the
circuit board. Adequate labelling should be attached to
warn service personnel, and others, that this danger
exists.
The control board assembly must be mounted, preferably
with the heatsink vertical, with sufficient free air flow across
its surface to prevent the heat dissipated in a number of
critical components from causing an unacceptable rise in
the ambient temperature.
The board should be mounted in a place that is clean and
dry at all times, not subject to condensation or the
accumulation of dust and other contaminants.
