There have been a lot of arguments about starter nowadays. Some people tried their very best to hide it, some think it is not necessary, and yet some insist they should have one. Starter is not part of air conditioning system but yet it is a necessary device in any air conditioner installation. Let’s find out why it that so. There are 2 main functions that starters perform: a. As a device to limit running current b. As a default off switch The first function is to protect against electrical overloading and overcurrent. Overloading may be caused by dirty coil, faulty wire, loose wiring connections, irregular power supply, etc. The thermal overload protector act as a device that will trip the unit should there be high current. This is to prevent fire hazards as well as to protect the compressor. The second function is to protect the unit when there is disruption in power supply. Imagine all the air conditioners in your area start at the same time when power supply is resumed.

The power pull will be tremendous, causing overloading and other power related problems. This is especially serious for air conditioner due to the power usage of compressor, where for split units, the starting current is 6 times the running current. Starter act to cut off supply to the unit, so that the air conditioner will not start automatically by itself. TNB regulation stated clearly that a starter is required for air conditioners. Therefore it is illegal to bypass a starter. Up until Built-In starter, mechanical starters are used. However, in a mechanical starter, the setting of the overload protector is manually adjusted. The problem lies in settings that are not accurate or mis-adjusted. Air conditioners with different cooling capacity require different current setting. If this is not done properly, you may not get the right protection. On the other hand, Daikin Built-In starter settings are all pre-set in the factory, providing a safer environment. Most importantly, all starters must be approved by Jabatan Bekalan Elektrik Dan Gas, the regulatory body of electrical applications.

This air conditioning repair article explains procedures for the diagnosis and repair of hard-starting air conditioning compressors. If your air conditioner or heat pump compressor motor won't start or has trouble starting, humming at start-up for example, it may be damaged and at or near end of life. But a common repair performed to try to get such motors running and to keep them in use longer is the installation of an air conditioner or heat pump "hard start" kit - a start capacitor or a start/run capacitor that helps get the motor spinning. First it's useful to diagnose the cause of the compressor's hard-starting trouble.

Aircraft Ground power unit Electric Baggage / Cargo tractor Pneumatic & hydraulic equipmentJump Starter Power Station misplaced my ac adapter what input and output should I use to recharge example what should I buy I need to buy an ac/dc adapter, an extension cord is not going to do the trick. I need to know what kind on voltage and output I need.

The converter/adapter is lost . I would like to save the unit but do not know what size adapter to buy This a battery jump pack that is used to jump start a car. Some units have an ac adapter built in so you can charge the battery in the jump start pack. My unit has a spot to connect the ac adapter to the jump pack so you can charge the battery in the jump pack. My ac adapter has been lost. I know I have to buy a new ac adapter so I can charge my jump pack, what I do not know is if the input (from the ac adapter) is 120v 60 hz I understand that the DC output needs to dc12v. I do not understand the milliamps. The battery in the jump box is 12v 10 ah ( what ever that is). I just want a new ac adapter to charge the jump pack with that is not going to damage anything. /manuals/PS110...), this is the type of extension cord you need.
