Description

NEW Heavy Duty Power Supply Unit for Commodore 64 128 VIC-20 Plus/4 with Over Voltage, Under Voltage, Short Circuit, EMI, Thermal protections

BOM list https://www.digikey.com/en/mylists/list/ZIN8B06P1I

* PCB Thickness 1.6 mm

* Outer Copper Weight 2 oz

* Surface Finish ENIG

* Gold Thickness 2 U"

Selector for 110/115VAC and 220/230VAC.

High-efficiency solution:

12V DC input, room temperature, still air:

95% efficiency at 5.15V / 0.5A

96% efficiency at 5.15V / 1.5A

94% efficiency at 5.15V / 3.0A

92% efficiency at 5.15V / 4.0A

Excellent line (from 10V to 13V, at full load) and load (from 0.4A to 4A, R/F 40us, duration 300ms) regulation and transient response: ±0.25%

Output adjustable up to 5.12V~5.38V (5.25V ±2.5%)

recommended: 5.15V when sitting idle at the "Ready" prompt

Overvoltage protection >5.49V ±0.30V

Under voltage protection <6.96V ±0.12V

Overload and Short-circuit protection, Thermal shutdown, fused transformer's primary and secondary coils

with Power ON, Good and Fault monitoring and signaling.
