Moduli buffer open frame in grado di offrire 380ms di hold-up time supplementare per alimentatori con tensioni di uscita 12V, 15V o 24V
Postato : 18 Feb 2021
TDK Corporation (TSE 6762) announces the introduction of the open frame ZBM20 buffer modules with the capability to provide 380ms additional hold-up for 12V, 15V and 24V AC-DC power supplies. The extended hold-up time allows equipment to safely shutdown and avoid data loss. Applications for the modules include industrial automation, robotics and semiconductor fabrication equipment.
To avoid unsafe discharge of stored energy, the remote on/off function can be used to inhibit the output. For remote monitoring, a DC OK relay and photo-coupled signals indicate the readiness status of the product. Multiple modules can be paralleled for longer buffer times. The hold-up energy is stored in electrolytic capacitors rather than batteries to remove the need for servicing and maintenance. On the 24V output model a switch can be used to select either fixed or variable voltage buffer levels. In fixed mode it will provide power when the input voltage drops to 22.4V, in variable mode when the input decreases by 1V.
The ZBM20 modules measure 175 x 85 x 57 mm (L x W x H), and will operate in ambient temperatures of -25°C to +70°C. The five-year warranty ZBM20 has protection against both input overvoltage and overcurrent conditions. Inrush current reduction and internal fuses are also provided. Safety certification includes IEC/UL/CSA/EN 62368-1 with CE marking to the Low Voltage, EMC and RoHS Directives.
