9900D Series

Built in N+1 redundancy

The 9900D series UPS has built in N+1 redundancy. The design adds one more module than required to support the critical load (“N+1” UPS). In an N+1 UPS configuration, two or more UPS systems deliver power to the critical parallel bus, which feeds the critical load. A failure in one UPS module would allow the UPS to remove itself from the critical bus, while the remaining module (or modules) supports the critical load. With the ability for N+1 configuration, the 9900D is a logical choice for mission critical applications where downtime is not an option.

Get clean, uninterrupted power with modular UPS

The 9900D series UPS delivers clean, consistent power to your critical load, regardless of the state of the incoming power source. Any power anomaly from the source is filtered through the UPS, so it is transparent to your critical load. This includes everything from a complete loss of input to the UPS to sags or spikes coming from the source. In all circumstances, the UPS will correct the anomaly and automatically provide clean, uninterrupted sinusoidal power to the critical load.

A typical single module UPS system has an MTBF (mean-time-between-failure) of about 2.6M hours using the bypass source as an alternate supply for the UPS and about 100,000 hours without factoring in the bypass. On average, the UPS will operate more than 10 years without transferring to bypass.

Compact Design

The 9900D sets a new footprint standard for hyperscale UPS, generating more white space and leaving more space to be allocated to revenue generating equipment. The 9900D maximises power output while minimising grey space for a more efficient UPS.

Superior Performance

At the heart of the 9900D is advanced power electronics. High speed sampling and switching delivers hyperscale performance, high levels of efficiency, increased cost savings, longer product life from cooler operation and the flexibility to operate in higher temperatures. The IGBT power device for the 9900D achieves superior function under all load conditions. All of this has helped the 9900D series achieve a sustained load carrying capacity of 99.9995% of (confirmed from operational history).

Expandable and Flexible

The 9900D’s modular design enables supplemental modules to be added over time to meet increasing capacity needs, making hyperscale expansion faster, easier and more economical. You can optimise investment by only paying for the power you need while retaining the option to expand the UPS capacity as your business grows. The modular design also allows for N+1 configuration.

Self-load Test Capability

The 9900D features a self-load test mode of operation, providing the ability to run burin-in tests on the UPS without needing an external load bank connected. This removes the need to rent a load bank and cables and reduces set-up, labour and utility power usage.
