Description
The GPT-9900 series is built upon a platform of AC 500VA maximum power output. The GPT-9904 is a 4-in-1 model capable of performing AC withstanding, DC withstanding, insulation resistance and ground bond tests, whereas the GPT-9903A is a 3-in-1 model capable of performing AC withstanding, DC withstanding and insulation resistance tests. The GPT-9902A is capable of performing both AC and DC withstanding tests whereas The GPT-9901A is able to only perform AC withstanding tests.The GPT-9900 series safety tester follows every good feature and advantage of the GPT-9800 series. The high-efficiency PWM amplifier is the core of GPT-9900 platform design to impede the influence from the voltage fluctuation of input AC source.
