Hartland Controls 的 HCT 系列耐用型變壓器可透過磁感應，將一種 AC 電壓變為另一種 AC 電壓，使其適用於各種應用。

Hartland Controls 的啟動電容和運轉電容具有滿足各種暖通空調電氣負載要求的內部結構。

Hartland Controls 的 HCC 系列接觸器是遙控／電動開關，由用於打開和關閉外部電路的觸點組成。

Hartland Controls 的繼電器屬於電磁開關，由一個電路中的低功率訊號或電流啟動，以打開或關閉另一個電路。

Hartland Controls 的 HHS 系列馬達硬啟動電容套件可消除一般在啟動時發生的溫度飆高，藉此提高暖通空調設備的效率。

Hartland Controls' Basic Relay Terminology Guide

A contactor usually has both moveable and fixed, low resistance contacts which do the actual circuit opening and closing.

Contact bounce is the uncontrolled opening and closing of the contacts due to forces within the relay (internal forces), whereas contact chatter is the uncontrolled opening and closing of contacts due to external forces.

故障的電容相當容易目視判別，例如冷氣機裡的電容衰退時，就會出現特定徵兆。

A transformer is a passive electrical device designed to change one AC voltage to another by magnetic induction.

Capacitors come in many different shapes, sizes and materials. They're used in a wide range of applications, including electronics, appliances, transportation and power grids worldwide.

From everyday applications such as refrigerators and garage doors, to signaling and protecting electrical power systems, relays are in use every second of every day.

Capacitors are attached to motors and constructed to release electrical power in different methods. The energy can either be released instantly to start the motor, or released over a period of time to keep it running.

Power contactors are used in large equipment for motor controls.
