Each model provides two main outputs and a CH3 output rated at up to 6 V, 5 A and 30 W. Select the main-output voltage and current combination needed for the device under test.\u003c\/p\u003e\n\u003cp\u003eCH1 and CH2 have the same rating within each model. Choose TK6332A for 30 V \/ 6 A on each main channel, or TK6333A for 60 V \/ 3 A. All three models retain a separate 6 V \/ 5 A \/ 30 W CH3 output. Series or parallel use requires external wiring and settings within every participating channel’s limits.\u003c\/p\u003e\n\u003ch3\u003eModel comparison and specifications\u003c\/h3\u003e\n\u003cdiv
