Heater broken alarm FAL-10G＜single phase,three phase dual use＞
■Operating priciple
1. Direct line current of load by current detector (C.T)
convert it to voltage, and enter division circuit
2. The line voltage of the load is detected by the voltage detector(Tr2),
and, it enters the division circuit through the current setting unit
and the alarm setting unit
3. Divide circuit compares and divides both inputs, drives a relay
through a Schmitt circuit , and issues an alarm output
4. Since voltage and current are detected even if the power suplly changes
both increase and decrease at the same rate.
Due to this change no warning will be issued even if the current decrease.
Therefore this equipment can be applied even by using a power
supply device by thyristor phase control or the like.
5. The malfunction prevention circuit operates when the load voltage
is 15% (15V when rated 100V,30V in the case of 200V) or less
and the alarm output does not come out.
Heater broken alarm FAL-10G＜single phase,three phase dual use＞
■Characteristic
● Phase control,ON-OFF control,Zero cross control,etc can be used
regardless of the total
● One heater burnout detection in parallel heater
● Detection points can be set arbitararily by dual scale
● When the detection point is reached,"ALARM LP"lights,and an output
signal is emitted
● Three phase circuit is also OK with this one
● Panel mounting type(DIN rail only)
● RoHS compliant products
