1. Power supply sequencer: Power supply sequencer is a sequencer used to control the on/off of electrical equipment, which can effectively manage and control electrical equipment in a unified manner.

The role of the power sequencer:

The power sequencer can start the power supply in order from the pre-stage equipment to the post-stage equipment, and close all kinds of electrical equipment in the order from the post-stage to the pre-stage when the power supply is turned off, so that all kinds of electrical equipment can be effectively managed and controlled in a unified manner, and the human error operation is avoided, and the impact of the electrical equipment on the power supply network at the moment of switching can be reduced at the same time, and the impact of the induced current on the equipment is also avoided, and the stability of the entire power system is ensured.
In general, the power sequencer is indispensable for the whole project, but the traditional power sequencer works in a single way, just following the orderly principle of switching on and off the equipment, in the current intelligent era, the traditional power sequencer is also necessary to be sublimated to meet the needs of more "intelligent control".

The power sequencer, simply put, is through the internal control circuit of the equipment, according to the established program to turn on or off the power output in turn, and the power supply management of the power supply voltage and load equipment, can accurately monitor the voltage, the volume is getting smaller and smaller, from 1U to 3U standard racks, mainly 8, 10, 12, 16 channels, etc. It is widely used in automatic control, TV broadcasting system, audio broadcasting, power facilities and other systems.
In audio equipment, the correct shutdown procedure is to turn off the power amplifier first, and then turn off the exciter, crossover, mixer and other pre-amp equipment in turn; The order is reversed when powered on. In order to prevent the noise impact generated by the pre-amp equipment and damage to the speaker and the amplifier. Using power sequencer, access to different switch sockets, you can realize from the pre-stage equipment to the post-level equipment, start the power supply one by one, and turn off the power supply on the contrary, effectively and uniformly manage and control all kinds of electrical equipment, avoid human error operation, reduce the instantaneous impact of the electrical equipment switch on the power supply grid, and ensure the stability of the power system.
2. Cloud Intelligent Power Manager:
Geffen Technology's GEFFEN Smart Power Manager is not just a simple power sequencer, not just a network relay, but a management center that can be controlled by any programming. It can manage eight high-power power supplies, each containing an anti-electromagnetic interference filter, a separate detection of the return current, voltage and temperature sensors, and a total power detection and calculation function

It has 1 LAN interface and access network interface, so that your device layout is full of imagination. It can be used with programmable host or PC communication to realize the control of a variety of peripheral devices. For example, it is used to control lights, sound sequencers, electric screens, electric curtains and projectors and other peripheral power supplies.
