DESCRIPTION

The ACB-3000 is an ultrafast dual-line static transfer switch that selects the appropriate line when a failure occurs. It continuously monitors the waveform of both input lines and, if the active line deviates from specifications, switches to the other line within 2 ms. This rapid response is achieved through a fully digital control combined with advanced SiC MOS power switches. Designed for both industrial and railway environments, the ACB-3000 is compatible with the Premium ODS -750, ODS - 1500, and ODS-3000 inverter families. In case of any failure, the unit indicates it locally via an LED and remotely via a solid-state relay and a CANopen bus port. During normal operation, the active input line is indicated by a blinking LED. When the other input line is properly powered, its LED remain s illuminated. Similarly, an illuminated output LED confirms proper operation. The switching occurs when the active input line has any of the following events: 1. Frequency out of range (10%). 2. Instantaneous undervoltage detection (20% of voltage). The response time is 1ms. 3. Voltage out of the safe zone: As indicated by the ITI curve in the figure, if the active line voltage moves beyond the defined “Safe Zone” for longer than the permissible duration, the system triggers a switching to the other line. The yellow zone represents a warning area, where a rapidly blinking LED alerts that the voltage has deviated more than 10% from its nominal value. 1 2 3 4 5 6 7 8

Redundancy static transfer switch 22-09-2025 CA-637-15 www.premiumpsu.com Powering Your Challenge When both input lines are within their specified ranges, input 1 is automatically selected as the active input by default (this setting can be configured via CAN). Conversely, if both input lines fall outside the acceptable ranges, the output is disconnected from both inputs. OVERLOAD PROTECTION The device is protected against overloads and short-circuits through a current-limiting circuit. When an overcurrent is detected, the failure LED is on, and the power switches turn off. The unit will attempt to restart every second, up to 3 times after the overload detection (configurable by CAN) . If the overload persists, the output remains disabled until a manual reset is performed by pressing the RESET button. The device can handle demanding conditions, sustaining twice the RMS current for 100 ms. Furthermore, as shown in the lower graph, it can withstand higher transient surges for shorter durations, ensuring robust and reliable performance during transient load conditions.
