Sentinel Tower
Sentinel Tower (STW) is the tower-form-factor twin of the Sentinel Dual SDU — same online double-conversion topology, same kVA-equals-kW (PF 1) sizing, but tower-only rather than rack/tower convertible. Single-phase 1:1 variants cover 5, 6, 8 and 10 kVA; three-phase 3:1 variants cover 8 and 10 kVA. All variants are parallelable.
Communication coverage matches the SDU — SNMP up to version 3, plus Modbus and Jbus — so the unit fits both IT and industrial deployments. Source positioning lists small and medium data centres with high power density, security and fire systems, medical equipment, and PLC/industrial use as typical applications.
Sentinel Tower [defines] Online Double-Conversion Sentinel Tower [relates] Sentinel Dual SDU
When to choose this
- Tower deployment preferred over rack — floor space available, no rack infrastructure
- Critical loads in the 5–10 kW class
- Need for parallelable redundancy (1+1, N+1)
- Three-phase supply with single-phase critical loads (3:1 variants)
