Military environments demand robust uninterruptible power supply systems. These military-grade UPS systems need to be field-proven and tested under various demanding and extreme environmental conditions. Companies that manufacture and supply them incorporate rugged packaging technologies and high-efficiency designs.
These systems can accept a wide range of frequency values & input voltages while delivering consistent AC output to the load. Most of these UPS use lithium polymer batteries that permit low weight and profile solutions in their power class. They are designed and built to comply with a broad range of military standards.
Military-Grade UPS System Features
While there are many different systems available for diverse military applications, some features that these UPS could have included:
- Shock-proof, waterproof and sealed construction
- Die-Cast Aluminium Chassis to endure demanding environments
- Output power of 1500 VA (1250 W) – 3000 VA (2500 W)
- Can operate at full power in these temperature ranges-20°C to +55°C
- Online double conversion function
- Full power operation (Shallow Rack) in these temperature ranges -20°C to +50°C
- Universal AC input of 80 to 265 VAC and 47-65 Hz
- >10 minutes of runtime at full power
- Has a storage temperature range of -40°C to +65°C
- Lithium polymer internal battery pack (hot-swappable)
- Dual input function AC and optional DC capability
- Power factor correction option at Alternating Current input
- Cold-start without AC/DC input connections
- Pure sinusoidal Alternating Current output voltage (115 VAC and 60 Hz)
- Able to handle non-linear and power factor loads of 0.0 – 1.0
- Configuration and User I/O signal ports
- Possible to combine up to 3 units for 3-phase AC output, higher voltage, or power
- Multiple units can be combined to create a glitch-free, fault-tolerant, higher power system
These are very generic and standard features that military-grade UPS systems could have. However, almost all of these systems are configured and customised to meet client requirements.
Modular Stacked Uninterruptible Power Supply
These systems allow end-users or design engineers the flexibility to re-configure the power services as required to meet the operational demands of harsh, deployed environments. The modular stacking capability considerably boosts the operational flexibility of the UPS systems. It also allows for the incorporation of a plug-&-play function (either redundancy or resiliency), to ensure that these operationally-critical applications have sustainable power management solutions.
Most of these systems are also designed to exceed many years of operational support without the need for battery replacement or system failure. This functionality ensures enhanced operational support, considerable reductions in logistical support, and related costs.
There are several online UPS systems available that are rugged enough to suit demanding military applications. These systems have to be 100% compliant with different electrical and military environmental standards. There are various configurations and types of systems to choose from, such as:
- Rack-mounted
- Rackmount double-conversion
- Freestanding
- Online
- Custom true online
- COTS online
Customised Military UPS Systems
Customisation options help to ensure that the configurations suit settings that have space constraints and these systems accommodate standard voltages as well. Many of these models can also function as frequency converters, altering the given input frequency & voltage to a different pure sine wave frequency and output. This runs in conjunction with the standard battery back-up capabilities.
