Intelligent power management

Intelligent, intuitive and already proven in the field worldwide, TSL’s PMU’s can monitor and manage power requirements from anywhere in the world while reducing overall costs - a combination that prevents system interruptions while

simultaneously reducing costly energy wastage.

Within the PMU family are two main units, the MDU12-PMi and the MDU12-PAi. Both units include the ability to manage power consumption via remote Ethernet control of 12 separate outputs via secure Web browser. The only difference between the two is that the PMi version has relay-switched outputs while the PAi is targeted solely at monitoring current and power operations. The advantage of relay-switched outputs is that energy costs can be saved when out of operating hours by switching off non-essential equipment - also conserving backup energy supplies when operating on backup sources by leaving only essential equipment running. Once again, this can all be controlled remotely, from anywhere in the world so providing essential control of unmanned operations. This includes the ability to reboot equipment if necessary by power recycling, as well as the ability to set limits for over/under current for each and every output so any error conditions are flagged for attention. When power is restored, or changes are required for the demands of alternate shifts, the MDU12PMi units are fully capable of automating a sequential or delayed start in a predetermined and carefully controlled fashion, making the often delicate job of powering up a system a far more efficient task

both in terms of confidence and cost- effectiveness.

It’s also worth mentioning that all TSL PMU’s are fully RoHS and WEEE compliant, which are vital aspects of any broadcast equipment consideration.

Smart software

The PMU range has a built in Web browser with industry standard SNMP management software that provides an intelligent GUI that includes a status page which shows all input and output alarm states, current, watts and power factor for each output, plus total power for each unit.

The implication of employing SNMP in the TSL MDU range is that it allows any other network application, from alarm system to email programs, to react and/or respond to messages sent from the MDU allowing instant notification of any equipment or mains failure by email, text message or, for example, an audible alarm. The GUI includes easily accessible and intuitive pages. The SNMP page is designed for setting up SNMP trap alarms to IP addresses configured in the SNMP setup page when a GPI in/out changes state, a fuse fails or is replaced or internal rack temperatures exceed or fall below threshold limits. The systems page allows the user to make choices as to whether to switch on all circuits immediately, enable delays set in the output page, or start up circuits sequentially by setting a circuit-by-circuit delay. The input page is where GPI alarms can be named and where choices can be made to set each circuit as ‘normally open’ or ‘normally closed’. On the output page names may also be changed and individual circuits can be remotely switched on or off from anywhere in the world.

If you want to keep your power - and system - under control, no matter where your equipment is located and no matter who is responsible for

maintaining it, even for unmanned locations, examine your existing power

management system and determine if it’s really

doing the job you need it to.

Further across the range

In addition to the MDU12PM range, TSL also offers the MDU-14CO, which has two auto changeover inputs and 14-way outputs for critical change- over switching between main and backup power sources in the event of mains failure - so ensuring 100% uptime. Its stablemate, the MDU 2CO, is designed specifically to work in tandem with either the MDU-12PMi or PAi to have complete protection and system visibility.

Also true to form, all our products are designed to meet the challenging safety specification BS-EN-62040-1- 1:2003 which governs Uninterruptible Power Supply (UPS) products.

Summary

These TSL-developed power management units are built to offer reliable and user-friendly operation. We also ensure that our customers are thoroughly informed on how to get the best out of the equipment they purchase, and that they are making the right choices for the tasks they wish to perform.

If you want to keep your power - and system - under control, no matter where your equipment is located and no matter who is responsible for maintaining it, even for unmanned locations, examine your existing power management system and determine if it’s really doing the job you need it to. There’s good chance that it isn’t, but there’s an even better chance that - with the right equipment and a global approach to power management - uptime guarantees and cost savings targets can be met in a way that will continue to pay dividends for many years to come.
