DIN-A-MITE Solid-State Power Controller

0600-0025-0005 Rev H Made in the USA

February 2007 $10.00

Please consult this user’s manual when you
place your new DIN-A-MITE into service. It
contains all the necessary information to mount
and wire the product into the application. This
manual also contains all user-pertinent
specifications and semiconductor fusing
recommendations. Refer to national and local
electrical code safety guidelines whenever you
install electrical equipment.

This DIN-A-MITE product is capable of
switching up to 40 amps single-phase; 33 amps
3-phase, 2-leg; and 22 amps 3-phase, 3-leg at
600V

Å (ac). (See the output rating curve in the

specifications section of this manual.) The DIN-

A-MITE is electrically touch-safe, and includes
DIN rail or standard back panel mounting. An
optional shorted SCR (silicon controlled rectifier)
alarm feature is available on specific models.

The Watlow DIN-A-MITE alarm
option provides a common alarm
output for shorted SCR conditions.

This is a non-latching alarm.

A shorted SCR alarm is detected
when there is no command signal
and a load current is detected. The
alarm output is then energized.

System Wiring Example

Latching Alarm Option
(models DB _ _ -

Alternative Latching Alarm Circuit

If there is a need for a latching alarm, the DIN-A-MITE alarm circuit
could be used as shown at right in the latching alarm example. If the
DIN-A-MITE triac alarm output energizes, it will energize the RY1
(external alarm relay) mechanical relay coil. Once the RY1 coil is
energized it will latch on (via the RY1A normally open contact) until the
power to the relay is removed. You could cycle the power via a reset
switch. The RY1B contact can be used for alarm signaling.

Shorted SCR (silicon-controlled rectifier) Alarm
Non-latching Operation

The shorted SCR detector compares the input
command signal and actual load current. If load
current is present without an input signal then the
shorted SCR alarm will energize the alarm triac
output. This is a non-latching alarm. This output can
be used to drive various indication devices, such as a
coil, light, buzzer, etc. See the alternative latching
circuit section below.

An external EMI filter must be used in
conjunction with the DIN-A-MITE for
loads in excess of six amperes (6 A) at 150
to 250 kHz. Without a filter applied, the
DIN-A-MITE does not comply with the
conducted emissions standard for loads
above 6 A at 150 to 250 KHz.

Watlow has verified that two types of
filters will suppress electromagnetic
interference (EMI) created by the DIN-A­MITE power controller to within the CE
requirements.

A tank filter supplied by Crydom or
Watlow, installed across the power lines,
suppresses EMI on the power lines.
See Figures 1 and 2.

See Table 1 for the correct filter.

Table 1— DIN-A-MITE EMI Filters.

çWARNING:

The isolating and tank filters specified may suppress
desirable communications carried on power lines in
the 150 to 250 kHz region. The filters may suppress
carrier current such as that used for infant monitors
and medical alert systems. Verify that suppressed
carrier current or other desirable communications on
power lines creates no hazard to people or property.
Failure to observe this warning could result in damage
to property, and injury or death for personnel.

ÓWARNING:

All filter installation and wiring must be performed by
qualified personnel, and conform to local and national
electrical codes. Failure to observe this warning could
result in damage to property, and injury or death for
personnel.
