The 20021380-001 Power Kit is designed for 100-120 VAC Series 49UL heaters. The power kit comes with an 15 foot power cable with a NEMA 5-15P plug and IEC-C15 connector. Series 49 UL power kits also come with a power adapter and male and female termination plugs. The power adapter supplies power to a chain of Series 49UL controllers and provides for communications pass-thru to adjacent upstream and downstream controllers. The power adapter includes a ground lug that can be connected to the chassis of the system, for system grounding. Each power kit can supply up to 10 Amps of power. Multiple power kits may be required based on the total current draw of the heater jackets in the chain.
