The Instek GPL-5010 Transient Limiter for GSP9330 is commonly used to test electromagnetic interference. For EMI testing, when accidentally overloaded, it can protect the terminal circuit and the valuable EMI test equipment. Meanwhile, together with our GLN-5040A Two Line VNetwork, they constitute a complete EMI test system. It can be used in Power supply (switch type and linear) design, Inverter/transformer design, and LED illumination design.
