Triac controller for proportional control
of electric heating
PULSER/D is a proportional controller for electric heating with auto-
matic voltage adjustment. PULSER/D pulses the whole load On - Off.
The ratio between On-time and Off-time is varied 0 - 100% to suit the
prevailing heat demand. The current is always switched at zero phase
angle to prevent RFI.
PULSER/D is only intended for electric heating control. The control
principle makes it unsuitable for motor- or lighting control.
PULSER/D cannot control 3-phase loads.
PULSER/D is intended for DIN-rail mounting.
Mount PULSER/D on a DIN-rail in a cabinet or other enclosure.
Mount PULSER/D vertically with the text right side up.
Protection class:
IP20
Ambient temperature:
0 - 40°C
PULSER/D emits approx. 20W of heat which must be dissipated.
Wiring
Supply voltage
Terminals 1 and 2. Not polarity sensitive.
Supply voltage: 200 - 415V AC, 50 - 60 Hz with automatic voltage
adjustment.
Maximum current 16A.

Figure 1: Wiring of supply voltage and load
The supply voltage to PULSER/D should be wired via an allpole
switch with a minimum contact gap of 3mm. PULSER/D must be earthed.
Load
Terminals 3 and 4.
Resistive single- or two-phase heater.
Maximum load:
3680W at 230V (16A)
6400W at 400V (16A)
Minimum load:
230W at 230V (1A)
400W at 400V (1A)
External sensor and setpoint (figures 2-6)
Terminals G1, G2 and G3. Not polarity sensitive.
The choice of terminals is determined by whether the internal set-
point is to be used or not.
If the internal setpoint is to be used the sensor is to be connected to
terminals G1 and G3.
If an external setpoint device is used, use terminals G1 and G2.
The PULSER/D sensors have high potential compared to neutral
and earth (>200V). Thus, wiring and installation of the sensors must com-
ply with local codes for line voltage installations.
