Trio
power supply board specifications:
• AC input voltage:100~250 VAC
• AC input current: <1.6 A
• AC voltage frequency: 50/60 HZ
• Two-way output voltage: 5 V/12 V, normal working current is 1.5 A for 5 V, 2 A
for 12 V
• Two-way output voltage has functions of short-circuit, over-current and over-voltage
protection
• The power board has reset function
• The power board can manage the charging process of lead-acid battery
(12 V/ 2.3 AH). The charging time is 8 hours maximum.
NOTE:
Power Supply Board must be connected to resistive load to
operate properly and avoid damage due to an overcurrent
condition.
