Application
The Controlled Laptop Charger is a purpose designed power management system providing both continuously
powered and controlled AC sockets. This design enables vital equipment such as cooling systems or switching
equipment to be powered from the same PDU (Power Distribution Unit) as controlled equipment such as laptop
power adaptors while providing energy savings through timer controlled cycles.
The Controlled Laptop Charger in designed with 4 modes; Disabled, Staged On, Constant Cycle and 12 hour
Cycle, allowing for usage in a wide range of applications. The Disabled mode provides a low power option only
powering critical equipment, while the Staged On mode reduces the peak inrush current reducing the
probability of tripping sensitive circuit breakers. The two cycle based modes provide significant power savings by
reducing the powered time of each controlled socket by up to 91.7% of that of a constantly powered socket.
Installation
The installation procedure for the Controlled Laptop Charger is as follows;
1. If rack mounting is desired, the Controlled Laptop Charger may be screwed directly onto 19” mounting rails using
two M6 screws and cages nuts on each side. Two mounting configurations are possible for the 1.5 RU power board.
Use either the top and lower central hole for a flush top fitting, or the bottom hole and upper central hole for a flush
bottom fitting.
2. Plug in but do not power the PDU’s power cord.
3. Plug in all appliances to be powered by the power board.
4. Finally power the PDU and set the mode according to requirements.
WARNING:
If the supply cord is damaged, it should be replaced by a Precision Power Products agent to avoid
potential safety hazards.
Setting the PDU’s Mode
The mode button (as seen in Figure: 1) when pressed, cycles through the 4 available modes. Each time the mode
button is pressed the mode light will remain lit for 4 seconds during which the PDU will apply the new setting. Any
subsequent press will reset the delay timer. Once set you can identify which mode is in use according to the mode
LED sequence described in Table: 1.
