ZonIt MicroATS 1.8m 8A - 1 x C13 - Dual C14 Input

ZONIT μATS™ Micro-ATS Micro Automatic Transfer Switch

The μATS is the world's smallest and most efficient capable Automatic Transfer Switch for datacentre equipment. It enables a completely different approach to the deployment of power in the datacentre. The device is a zero "U" self-mounting device that is designed to auto-switch the power fed to Electronic Data Processing equipment.  It utilizes unique patent-pending technologies to provide unparalleled functionality.

Single power IT devices easy to retrofit with redundant power supply

The Micro Automatic Transfer Switch (μATS™) from Zonit, which doesn’t take up any space in the rack (zero U: device), is the world’s smallest and most compact transfer switching solution that makes it easy to retrofit existing servers and network components with a redundant power supply. This is done simply by connecting the Zonit μATS™ to the central power supply of a network device and establishing a physical connection to an A and B circuit. During normal operation, the Zonit system gets the power it needs to feed the components exclusively from the A circuit. If this circuit fails, the transfer switch automatically switches to the B circuit in just 9 to 11 milliseconds – i.e. ten to twelve times faster than the blink of an eye – and regardless of the phase angle. This circuit then supplies the connected components with all the power they need until the A circuit is ready again to assume the full load. The circuit doesn’t just switch from A to B if the A feed is completely down: even in the event of impending AC frequency increases or overvoltage or undervoltage, the Zonit transfer switch changes from the A to B feed until an acceptable level of power quality is reached again with A.

The Zonit μATS™ solves many common problems with power distribution and enables new and highly efficient patent pending methods of power distribution. The Zonit µATS™ has five primary usage scenarios: 

1.    Redundancy - Enables redundant power feeds for single power cord devices 

2.    99.9% Efficient Power Distribution - Saves 3-15% of annual data center power costs

3.    Increase UPS Efficiency by 3-5% - Saves 3-5% of UPS power conversion losses

4.    Cost Effective N+1 Reliability - Eliminates the need for 2nd power supplies in N+1 horizontal server tiers

5.    Re-Location Flexibility - Allows easy “hot moves” to relocate powered-up equipment. Ideal for doing deployments that are temporary or will be moved at a later date.

Why use the µATS?

The µATS™ allows single power supply devices in the datacentre to be connected to redundant A-B power sources. This eliminates one of the primary causes of downtime, human error. Much downtime is caused by people plugging in one too many devices to a branch circuit, causing its circuit breaker to trip.

The Zonit µATS™ is very useful to increase the service level availability of common single-power devices such as network distribution switches, firewalls, and other equipment that may be in a mission-critical service path, sometimes unknowingly.

The µATS™ enables much easier maintenance of redundant power systems, since one source can be taken off-line if all single power supply devices are fed via µATS™ units.

Data & server racks with single power supply network switches especially benefit from the Zonit µATS™, because it enables a UPS unit in that closet to be taken off-line for battery testing and maintenance during regular business hours without network service downtime.

99.9% Efficient Power Distribution

The Zonit Micro ATS (μATS) enables 99%+ efficient power distribution methods in the datacentre. It allows datacentre devices to be preferentially connected to filtered utility power on the A side and an Uninterruptible Power Supply (UPS) on the B side, which is only used when A is down. Eliminating UPS power conversion losses saves 3-15% of datacentre power usage compared to redundant UPS designs, which can save millions of dollars in energy costs. The µATS™ is 99.75% efficient, using only 125mA in normal operation. This maximizes datacentre Power Utilization Efficiency (PUE).

Modern computer power supplies are almost all auto-ranging (accept 110-240V input) and all switched (Draw on the Alternating Current [AC] input power for just a short period of time and then convert this energy to Direct Current [DC], then repeat). Power supplies of this type are more resistant to power quality problems, because they only need to “drink” one gulp at a time, not continuously. If the input AC power voltage range is controlled within a known range, they will function very reliably. They do not require perfect input AC waveforms to work well. All that is necessary is that they receive sufficient energy in each “gulp” and that the input power is within the limits of their voltage range tolerance. This makes it possible to use a datacentre power distribution system that is much more efficient than a fully UPS supplied power system at a very reasonable capital expense.

The power system design shown above controls voltage ranges very well. It has been in use for many years. The Zonit µATS™ enables new power distribution methods coupled with this power system design that are very efficient.

Zonit μATS™ transfer switch highlights:

• Ultra-compact transfer switch with 1, 2 or 3 ports
• Zero U device
• Single-power devices are supplied with redundant power
• 8 A version for 208 to 240 volts
• Only 9 to 11 ms to switch from primary to secondary power supply
• Switch from A to B circuit regardless of phase angle
• Virtual circuit breaker with audio alarm
• Power supply automatically capped in the event of excess current
• “Hot walk” feature for simple relocation with interrupting the power supply

Available to retrofit a redundant power supply for 1, 2 or 3 IT devices with a single transfer switch

There are different versions of the Zonit Micro Automatic Transfer switch available. The standard single-port version has a C13 connector integrated at the switch. The 1-port "Y" model has a 22cm long cable at the C13 connector. 2-port and 3-port "Hydra" versions are also available. Both are particularly suited for use in highly dense environments. All versions handle voltages between 208 and 240 volts at up to 8 amperes.

Maximum protection of IT devices from overload, failure and damage

One of the safety features of the Zonit μATS™ is a patent-pending virtual circuit breaker that immediately triggers an audio alarm if the maximum current of 8A is exceeded. If the excess current continues, the Zonit transfer switch caps the power supply to protect the IT component and a red LED lights up to indicate the off status. It can be manually restarted with the restart button on the transfer switch chassis. Another circuit breaker inside the device is only triggered if, for example, the connected IT device short circuits. This means that the connected IT hardware has maximum protection from malfunctions, failure or even damage caused by power loss at all times.
