Rated Input Voltage

Operating voltage: AC176V-264V; Rated voltage: AC220V; Interface position: Three-position covered socket, labeled AC-L, AC-N, FG.

Rated Input Current

Rated current: AC 0.5A, current range AC 0.5～1A

AC Input Frequency

Rated AC voltage frequency range 47～63Hz, sine wave

Inrush Current

The inrush current to the power grid at the moment of power-on: the maximum value during cold start is 60A/10ms.

Output Overload Protection

The +12V overload protection point is approximately 105%~120% of the rated output power; the overload protection is an online current-limiting and voltage-reducing method; short-circuit protection requires input reset.

UPS battery management function

An external battery (5~30AH capacity) is required as backup power. When AC power fails, the system automatically switches to backup power with a switching time of ≤50ms. When AC power is normal, it automatically switches back to AC power and manages the battery (to enable the UPS function, BAT+ and BAT.SW need to be shorted).

It has the function of float charging external batteries (5~30AH), and the battery has undervoltage protection of 10V±0.6V and short circuit protection function with automatic reset when discharging to load.

Power supply timing parameters

Setup time ≈ 200ms; Settlement time ≈ 50ms; Hold-up time ≈ 20ms

Dielectric strength parameters

Input-output: >AC1.5KV; Input-casing: >AC1.5KV; Output-casing: >AC0.5KV; Leakage current <5mA; 50Hz; 1min.

Operating temperature parameters

The operating temperature drift coefficient is approximately ±0.03 [%/℃]; the absolute temperature rise coefficient is approximately 0.50 [℃/W]; the absolute temperature rise of the chassis when operating at rated power is 25℃±5℃.

Environmental conditions parameters

Storage environment: -20℃ to +85℃; 10% to 95%RH. Operating environment: -10℃ to +50℃; 20% to 90%RH. (Varies depending on the operating environment and power consumption)

Cooling method

Designed for continuous operation, with self-cooling and heat dissipation assistance. (Power consumption and lifespan are affected by differences in the usage environment and installation location.)
