Fire lighting PYD series single-phase power supply is a type of emergency backup power in the building equipment installation, when building a fire, accident or other emergency situations lead to the mains power failure, fire lighting, emergency power supply for the fire lights , lighting, and is particularly important to provide a second or third load standby power. With the improvement of building fire safety standards, especially the increase of high-rise buildings, fire lighting, emergency power supply has become an essential building fire facilities. In normal lighting, power was forced to cut power outage or fire power outages and other special circumstances, in order to ensure the safety of personnel quickly evacuated and rescue work, emergency lighting is very important. This product can be used in high-rise buildings, shopping malls, hospitals, underground air defense projects.

 

I. Principle

When the mains is normal, after each vote municipal electric system to power the load, while the spare battery charger intelligent charging. When the mains power, or more than 25% of the normal voltage, the inverter signal provided by the controller, start the inverter while each switch device will immediately switching to the inverter output continue to provide sine wave alternating current, when the mains voltage is normal, emergency power supply will restore electricity supply.

 

Second, the product uses

Under fire or other circumstances for emergency lighting and other lighting (metal halide, sodium) to provide centralized power supply emergency power unit is suitable for building occurs.

 

Third, the model explained

Description: Installation form, inlet and outlet (upper and lower), single / dual power supply, input and output phase, spare time, fire linkage, the number of output circuits are described in the order.

 

IV Features

1) centralized power supply mode, no special lights

2) When the emergency power supply, sine wave output, with voltage, frequency stabilization, noise

3) fire control, computer monitoring

4) LCD, LED display, at a glance

5) dual power automatic switching, high reliability

6) the use of single-chip control, to ensure that all action points accurately

 

Five Advantages

1) designed to be simple and easy construction

2) and lower total cost, investment

3) long life, the host life more than 15 years

4) Maintenance-free batteries can be recycled 300-500 times

5) automatic switching, can be unattended

6) Keep the lighting stable, reliable, easy to maintain

 

Six, the installation forms

Floor-standing, hanging, embedded type three

 

 

Seven, PYD series design schematics

 

Option One: Single Input Single power supply schematic

Note: When there is electricity, electricity output by KM1, while the charger to charge the battery when the power cut EPS detected or mains voltage is too low, the inverter work to make KM1 output state to switch to emergency load provide electrical power.

 

Option Two: Single Supply Dual Input Schematic

Description: The two-way mains input, usually by an external load control switch K can be opened relations. But EPS detects mains failure or mains voltage is too low to, regardless of the switch K at any position, can achieve emergency power.

 

Option Three: Dual power supply schematic (a)

Description: Under normal circumstances, the mains by KM2, KM1 output, maintenance-free battery charger for charging, when the mains power failure, the standby power input by KM3, KM1 output only when the common power and standby power outage at the same time when working through the controller so that the inverter output KM1 switched to emergency state, to provide power to the load, but when put into standby power for longer than the switching time of the EPS, EPS before this investment, such as backup power to, and then switch to exit , this way of each switch device in this EPS.

 

Option 4: Dual power supply schematic (two)

Description: The use of such wiring can achieve end load mutual investment level, EPS power to act as a third way, this way each switch device outside of the EPS.

 

Five programs: to act as a second way power dual circuit schematics

Description: EPS figure can serve as a connection to the second road load power, and the end of each vote, this way the inverter when there is electricity in the state is not on, when there is no electricity, there is immediately switched output, this way each switch device outside the EPS.

 

Eight, PYD series wiring diagram program

 

Option One: single-phase single-input single-phase multi-loop output wiring diagram

3) K, H for circuit breakers, do not belong to the company provides;

4) Z is switch.

 

Option Three: Three-phase input three-phase output, single-phase when emergency triple output wiring diagram

Wiring: persistent

Description: 1) the circuit breaker K can control multiple lighting normal working condition;

2) When the circuit breaker H no electricity when Z is converted to an emergency power supply for emergency lighting;

3) K, H for circuit breakers, do not belong to the company provides;

4) Z is switch.

 

Option 4: single-phase two-input single-phase dual output for multi-layer wiring diagram

Wiring: persistent

Description: 1) to control each circuit breaker K lights usually work status;

2) When the circuit breaker is converted to H Z without electricity emergency power supply for emergency lighting;

3) K, H for circuit breakers, do not belong to the company provides;

4) Z for the switch, located in the EPS products, L, N simultaneous conversion;

5) KM1 to convert AC contactor, located in this layer of lighting distribution box.

 

Five programs: Emergency lighting mixed wiring diagram
