The mounting holes are at 5. However all you xatasheet is to monitor the current flow trough one of the emitter resistors at the output of the power amplifier. Your email address will not be published. The buyer is responsible for any tax datqsheet duty charged on their country. Those can be quite bulky so the PCB is quite large. However those were using small current relays not suitable for more powerful amplifiers.

My speaker terminals have 5mm threads and fit just fine. There is no built-in circuit either. We will provide you with the best quality and most cost-effective products. But can you write all resistor values? I am wondering if this works for you Ventsislav? Almost any Sony amplifier starting from the lower range and right up to the higher-end ES series are using this chip.

Skip to content Skip to primary sidebar Skip to footer. Most power amplifiers have datashet dedicated circuit built in them, to monitor the current flow trough the power transistors. A wide variety of new original cha options are available to you, such as drive ic, voltage regulator, and logic ics. Thanks for posting such a nice speaker protection with really high class chip.

CHA new original electronics component ic. Relevancy Transaction Level Response Rate. Hi Ventsislav, Great article about a very usefull item which no one ever hopes to use. Upc Speaker Protection Board. There is a solution around this however, if you can provide a low power auxiliary voltage of about 18VAC. It was in fact used in many industry amplifiers. Thanks for your help. Contact For Datasbeet Shipping.

There are 54 new original cha suppliers, mainly located in Asia. The relay is located between the mounting pads to keep the paths equal and at the same length.

According to the datasheet pin 1 must be driven above 0. Hi, some of the resistor values depend on the supply voltage. The maximum allowed is 60VDC.

It can be downloaded HERE. Great article about a very usefull item which no one ever hopes to use. Hello Simonov, I am wonderig how did you compute resistors for first schematic over current protection? The mounting pads are of 15mm diameter. This will save space on the PCB, lower the cost of the project and increase the reliability.
