FAQ for G3PA-220B-VD-X DC5-24V
What's the difference between G3PA and G3NA?
G3PA: panel mount design, integrated heat sink mounting. G3NA: DIN rail or panel mount. Same electrical performance. Choose based on mounting preference.
Do I need heat sink?
Yes, for 20A load, heat sink is essential. Power dissipation: 1.6V × 20A = 32W. Size heat sink for your ambient temperature and load duty cycle.
Can I use this for transformer load?
Yes, but transformer inrush current can be 10-20× nominal. Ensure SSR can handle inrush. Consider soft-start circuit or SSR with inrush limiting.
What's the control input current?
7-15mA at DC5-24V. Compatible with PLC transistor outputs, microcontroller GPIO (with current limiting resistor).
