Power Sequence Controller

Figure 2 shows these phases for a typical system.

Power sequence controller.

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. Tiny footprint lm3880 2 9x1 6 mm. Each output s power up power down is delayed by a fixed amount determined by the front panel user definable sequence delay control.

Buy 8 outlet power sequencer conditioner 2200w rack mount pro audio digital power supply controller regulator w voltage readout surge protector for home theater stage studio use pyle ps1200. 115v input power with unique genderless connector. During up sequencing each power supply must wait its turn and then power up to the correct voltage in a designated amount of time.

The lm3880 and lm3881 simple power supply sequencers offer. The system is ideal for large sound reinforcement systems. Steel construction with black textured powder coat finish. Has an interval delay of two seconds between steps.

The art ps8 ii provides controlled power sequencing to eight rear ac outlets.

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 ltc2937 can control the sequence of up to six supplies while also monitoring power rail voltages. This allows you to co. Sequence up monitoring and sequence down.

Compatible with mpr series raceways. Like the lm3880 the ltc2937 can control the order and time delay of up to six power supplies or regulators figure 4. Sequence controller provides 6 step control to rlm modules. Power sequence controller 6 channel sacr 191 description.

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. One motor cannot start until some other motor is in operation. A power supply cycle has three operating steps.
