DIN-A-MITE Solid-State Power Controller

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 600VÅ (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. UL® 508-listed, C-UL® and CE with filter.
The DIN-A-MITE solid-state power controller is designed and manufactured by Watlow in Winona, Minnesota.

Latching Alarm Option (models DB – – S _ )
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.

Ungrounded Delta or Wye Load

Non-latching Alarm Option (models DB – – S _ )
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.

NOTE: Use a grounding conductor terminal plate (fork terminal) having upturned lugs or the equivalent to hold the wire in position. Maximum 6 mm2 (10 AWG) wire.
NOTE: The current transformer must be in the center uncontrolled leg on a 2-leg DIN-A-MITE.

• EN 61326-1: 2013 Electrical equipment for measurement, control and laboratory use – EMC requirements (Industrial Immunity, Class A1,2,4 Emissions) Not for use in a Class B environment without additional filtering.
• EN 61000-4-2:2009 Electrostatic Discharge Immunity
• EN 61000-4-3:2010 Radiated Field Immunity 10V/m 80 MHz- 1GHz, 3V/m 1.4GHz-2.7GHz
• EN 61000-4-4:2012 Electrical Fast-Transient / Burst Immunity
• EN 61000-4-5:2006 Surge Immunity (Reviewed to IEC 61000-4-5 2014)
• EN 61000-4-6:2014 Conducted Immunity
• EN 61000-4-11:2004 Voltage Dips, Short Interruptions and Voltage Variations
• EN 61000-3-2:2009 Harmonic Current Emissions (Reviewed to IEC 61000-3-2 2014)
• EN 61000-3-3:2013 Voltage Fluctuations and Flicker3 ≤ 16A
• EN 61000-3-11:2000 Voltage Fluctuations and Flicker ≤ 75A with conditional connection

NOTES

1. Use of an external filter is required to comply with conducted emissions limits. See note 4 below.
2. A Line Impedance Stabilization Network (LISN) was used for conducted emissions measurements.
3. To comply with flicker requirements, command signal models F0 and F1 will require a reduced source impedance. Cycle time on ON/OFF models CX, and K1, K2, K3 may need to be up to 175 seconds at 16A or have a reduced source impedance.

2006/95/EC Low-Voltage Directive
Required External EMI Filters for DIN-A-MITE with More Than 6 Amp Loads
An external ElectroMagnetic Interference (EMI) filter must be used in conjunction with the DIN-A- MITE for loads in excess of six amperes (6A) at 150 to 250 KHz. Watlow has verified that a tank filter will suppress EMI created by SCR power controllers to comply with the conducted emissions limits.

DIN-A-MITE EMI Filters

Description| Crydom Filter| Watlow Filter
Single-phase, 230VÅ (ac)| 1F25| 14-0019
Three-phase, 440VÅ (ac)| 3F20| 14-0020

WARNING: Tank filters 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 or injury to death for personnel.
WARNING: All filter installation and wiring must be performed by qualified personnel and conform to local and national electrical codes. In- line power filters have been shown to properly suppress EMI; however, these filters must be rated for the entire load current and are generally more expensive than the tank filter specified. An In-line filter may be required if carrier current communications are used on site.

Warranty

The Watlow DIN-A-MITE is warranted to be free of defects in material and workmanship for 36 months after delivery to the first purchaser for use, providing that the units have not been misapplied.
