Quality Power Supply
New product line SENTRY MPS-HP involves from 100 to 250 kVA models. SENTRY MPS-HP is an on-line double conversion UPS (IGBT and DSP) that guarantee maximum protection and high-quality output for any type IT or industry load. SENTRY MPS is designed as the new configuration whit using IGBT rectifier with sinusoidal input current. SENTRY MPS-HP is designed to protect “mission critical” applications (VFI SS 111 in accordance with IEC EN 620406-3) including data processing, telecommunications, industrial processes, security and electro-medical systems.
Minimum Impact on Supplies – Easy Source
SENTRY MPS-HP is a futher evolution of the SENTRY MPS series with the added advanteges offered by an IGBT-based rectifier assembly. This feature further reduces the impact of the UPS on the local supply and simplifies installation where there is limited power capacity in the form of available electrical supply rating or generator size. SENTRY MPS-HP is classed as “Zero Impact Source” and provides:
Low input current distortion – less than 3%
High input power factor 0,99
Power walk-in function that ensures progressive rectifier start up
Delayed start up phased with the return of mains power supply, when several UPS are connected in the system
SENTRY MPS-HP also performs the role of a high performance filter, protecting its upstream power supply sources from any harmonics and reactive power generated by the loads powered.
Battery care system
The SENTRY MPS-HP Battery Care System consists of a range of features designed to provide optimum performance and enhanced operating life
Flexibility
SENTRY MPS-HP models feature an output transformer with galvanic isolation (between the load and the battery supply)to provide greater versatility and installation options. The UPS can be supplied from two separated power source (mains power and a second emergency standby source) which can help increase the resilience of parallel system configurations.
Main characteristics
Efficiency up to 94%
Compact footprint: only 0,85 m2 for the 250kVA UPS model
Reduced weight
Double electronic and galvanic protection of the load from the battery
The entire SENTRY MPS-HP range is suitable for a wide range of applications thanks to the flexibility of the configurations, accessories and options and choice of performance levels. Efenciency and reliable power supply for mission critical applications isguaranteed by operating in redundancy and power parallel mode with up to 8 units (N 1), and by the Dual Bus System and Dynamic Dual Bus system configurations
