Rack STS Highlights for Dual-Source Power
Dirancang untuk menjaga power continuity pada IT load yang hanya memiliki satu power input namun membutuhkan dua sumber daya independen.
Fast Static Transfer
Transfer otomatis antar sumber AC dengan waktu transfer tipikal ≤4 ms untuk mengurangi risiko interruption pada critical IT load.
Dual Source Protection
Menghubungkan satu beban single-corded ke dua upstream source independen seperti UPS A/B, utility/UPS, atau dual power path.
Break-Before-Make Logic
Desain transfer BBM memastikan dua live feeds tidak terhubung paralel, sehingga transfer sumber tetap aman untuk beban dan upstream system.
High Efficiency
Efisiensi pada nominal power ≥99% membantu menekan power loss dan heat dissipation di dalam rack atau data center room.
2U Rack Form Factor
Form factor 19-inch 2U memudahkan instalasi di rack standard tanpa memerlukan panel eksternal besar.
Hot-Swappable Module
Static module dapat ditarik untuk maintenance setelah dialihkan ke bypass, membantu mengurangi downtime service.
Redundant Ventilation
Forced ventilation dengan redundant fans dan alarm membantu menjaga thermal reliability pada compact rack-mounted STS.
Protection & Alarm
Mendukung alarm kontak, status LED, EPO input, source failure indication, dan proteksi backfeed untuk operasi yang lebih aman.
