ZM IPC307 functions to identify inverter faults when a problem arises such as compressor over-current protection and shut down. It senses and measures valid switching operation of the 6 output transistors in inverter systems. A sequence in which all 6 transistors switch both on and off, is indicative of correct operation. The IPC is connected to the inverter instead of the compressor and automatically monitors the inverter output.<\/p>\n
The inverter uses a rectifier to convert the incoming alternating current (AC) to direct current (DC) and then switches the 6 transistors in a sequence to produce AC of a desired frequency. The variable frequency AC drives the compressor.
\nWhen an inverter system starts up – It is common for there to be a delay of typically two to three minutes before the output is enabled and the duration of the output switching sequence that follows, may only last for a second or more.
\nThe sequence is terminated once the inverter senses there is no compressor loading.
\nIn some cases the phase sequence might be repeated following a further delay. Also, following a fault, some systems will require a resetting action of some kind.<\/p>\n","protected":false},"featured_media":15954,"template":"","meta":[],"product_cat":[1117],"product_tag":[],"class_list":["post-15955","product","type-product","status-publish","has-post-thumbnail","product_cat-a-c-inverter-testing-instrument","first","instock","shipping-taxable","product-type-simple"],"yoast_head":"\n
