ò Operation responsivenessNone of the circuits has contact so that the response from the signal input to the electromagnetic clutch/brake output is fast and stable.

¢ Instruction for useò Protective deviceDo not enter a discharge device such as varistor on the output side (between P-C and P-B). If it is entered, an overcurrent trip will occur, which may cause operation shutdown or damage to the discharge device or power supply.

ò Protection functionA fuse is installed in the input side of the BES. When the fuse trips, it may be due to an error in the output side.• Short-circuit of the output side• Ground fault to the output side• Error of the output side (electromagnetic clutch/brake)

Before resuming operation, make sure there is no error in the output side.

¢ Specification

Design Check Items BES MODEL

ò Energy savingIt has zero stand-by energy and does not consume unnecessary power.When combined with our spring actuated type brake, it can achieve energy saving by reducing power consumption and heat generation of the spring actuated type brake by 70% or more.

ò Operation sound

The BES model has low-noise design. However, some excitation noise may be generated from the electromagnetic clutch/brake during operation depending on the installation environment. This is not abnormal, so there is no need to worry about it.

ò Two types of control method

Both PLC control that controls voltage with a sequencer and contact control that controls voltage with a relay are available for operation.However, for contact control, power control equipment is required in order to control the power line.

ò Power supply voltage variation and output voltage

The BES model is a power supply unit that is designed to operate successfully under fluctuations of power supply voltage. However, its output voltage fluctuates as the power supply voltage fluctuates. To satisfy the performance of the electromagnetic clutch/brake, fluctuations of the power supply voltage should be limited to within a range of ±10%.

ò Checking the output voltage valueWhen checking the output voltage with a voltmeter or tester, connect a load such as an electromagnetic clutch/brake in the output side.If not, the reading will be a value close to the power supply voltage.

¢ Connection method and time chart

��

¢ Installation of a protective device and equipment wiring are tedious. I need a simpler application.

¢ Easily broken relays. Short life-span of　relays. Several sparks that are unnerving.

The cause of destruction of a relay is back electromotive voltage (surge voltage) generated during magnet coil control. The back electromotive voltage exceeds 2kV without a protective device.This power supply unit controls the internal semiconductor relay (SSR function) with small input signals from the PLC (such as a sequencer). It realizes high reliability and longer life without any contact control device such as a relay provided by the customer.

This power supply unit incorporates a protective device.It also has the SSR (solid state relay) function, so wiring is simple as shown in the right figure. It requires no power control devices such as a relay and SSR, achieving cost reduction, small footprint, and less wiring.It can be installed on a DIN rail (optional), which is helpful for embedding into a control panel.

¢ ■I need better operation of a clutch and brake; I need to improve its life.

O ve r exc i t a t i o n c o n t r o l d r a m a t i c a l l y i m p r ove s t h e responsiveness of the clutch and brake. Also, it significantly extends the life of the clutch and brake.It has high output and a very compact size, and can be used for a wide range of clutch and brake models and sizes (refer to the correspondence table).

■¢ I need an environmentally-friendly power supply unit; I need to comply with the overseas standards.

I t has ze ro s tand-by ene rgy and does not consume unnecessary power.When combined with our spring actuated type brake, it can achieve energy saving by reducing power consumption of the spring actuated type brake by 70% or more. Also, it can reduce heat generation of the spring actuated type brake by about 70%, causing no heat damage in the peripheral devices of the spring actuated type brake.It complies with the RoHS directive and EC directive (CE marking).* For compliance with the EMC directive, use the EMC set (optional).
