Power Sequence Controller

A slightly more sophisticated power control device is the ltc2937 sequencer voltage supervisor from analog devices.

Power sequence controller.

Has an interval delay of two seconds between steps. Furman rs 1 remote system control of furman power sequencers keyswitch panel maintained contact on off sequence 5 0 out of 5 stars 3 30 76 30. Power sequence controller 6 channel sacr 191 description.

Discrete solutions with a combination of resistors and capacitors can provide power up sequencing but by themselves cannot provide a reverse sequence during power down. The system is ideal for large sound reinforcement systems. Compatible with mpr series raceways. The art ps8 ii provides controlled power sequencing to eight rear ac outlets.

Steel construction with black textured powder coat finish. A power supply cycle has three operating steps. Three steps of power supply control.

The sequential switch system applies power to system components in desired time delay sequence minimizing the potential for tripped circuit breakers blown fuses or voltage spikes caused by simultaneous power application. Sequence controller provides 6 step control to rlm modules. One motor cannot start until some other motor is in operation. Sequence up monitoring and sequence down.

During up sequencing each power supply must wait its turn and then power up to the correct voltage in a designated amount of time. Figure 2 shows these phases for a typical system. The ltc2937 can control the sequence of up to six supplies while also monitoring power rail voltages. Power up and power down sequence control.

Each output s power up power down is delayed by a fixed amount determined by the front panel user definable sequence delay control. Includes sequential restart functionality in the event of an outage. Sequence control is used by such machines as hydraulic presses that must have a high pressure pump operating before it can be used or by some air conditioning systems that require that the blower be in operation before the compressor starts. Tiny footprint lm3880 2 9x1 6 mm.

Like the lm3880 the ltc2937 can control the order and time delay of up to six power supplies or regulators figure 4. Sequence control forces motors to start or stop in a pre determined order. Lm3881 3 0x3.
