Lenze E70ACPSE0304S i700 Power Supply 30A

Lenze E70ACPSE0304S i700 Power Supply

Product Introduction

The Lenze E70ACPSE0304S belongs to the i700 series of power supply modules. Engineers use it to feed 400V AC input into drive systems. This model provides a rated output current of 30A. It also supports a maximum output current of 60A for short peaks. With a rated power of 10.3 kW, it handles many mid-range motor control tasks. Additionally, its IP20 enclosure protects against solid objects larger than 12mm. You can mount this unit directly inside a control cabinet. Because of its robust design, the Lenze E70ACPSE0304S ensures reliable operation in factories and workshops.

Technical Specifications

Input and Output Parameters

This power supply module operates with a nominal input voltage of 400V AC. Its continuous output current stands at 30A. For brief overloads, it delivers a maximum output current of 60A. The rated power reaches 10.3 kW. Therefore, it matches applications with fluctuating load demands.

Protection and Safety Features

The unit has an enclosure rating of IP20. This means you must install it inside a closed cabinet. It protects against accidental finger contact but not water or dust ingress. Overcurrent protection is built into the module. Also, thermal management ensures safe operation under peak conditions.

Mechanical and Environmental Data

Dimensions and Weight

Each Lenze E70ACPSE0304S weighs exactly 3.200 kg. Its compact footprint simplifies panel layout. The mounting type is fixed installation via standard screws. You should leave at least 50mm of free space above and below for cooling.

Environmental Operating Conditions

The module works in ambient temperatures from 0°C to +45°C. For higher temperatures up to +55°C, you must derate the output current by 2.5% per degree above 45°C. Relative humidity should stay below 95%, non-condensing. Moreover, the unit tolerates vibration levels up to 0.5g according to IEC 60068-2-6.

Installation Guidelines

Mechanical Mounting Steps

First, attach the Lenze E70ACPSE0304S vertically on a flat mounting plate. Use M5 screws for secure fixing. Next, ensure all ventilation slots remain unobstructed. Then, tighten screws with a torque of 3 Nm. Do not install the module close to strong heat sources.

Electrical Connection

Connect the 400V AC input to terminals L1, L2, and L3. Ground the PE terminal properly. For output, wire the DC bus to terminals +UD and -UD. Use copper cables with a cross-section of 6 mm² for input and 10 mm² for output. Additionally, apply a ferrule on each stranded wire end.

Common Installation Mistakes

Many users forget to check the phase rotation. However, the Lenze E70ACPSE0304S works with any phase sequence. Another mistake is using undersized fuses. Therefore, we recommend 63A gG type fuses in the input line. Finally, never disconnect the module while the DC bus is still energized.

Frequently Asked Questions (FAQ)

1. Can I use the Lenze E70ACPSE0304S with a 480V AC supply?

No, the nominal input is 400V AC. Voltages above 440V AC may damage the module. Use a transformer if your grid supplies 480V.

2. What happens if the output current exceeds 60A?

The Lenze E70ACPSE0304S will enter current limiting mode. It reduces output voltage automatically. If overload persists, thermal shutdown occurs after 10 seconds.

3. Is this module compatible with older Lenze i500 drives?

Yes, the DC bus output works with both i500 and i700 series drives. However, check that the total DC bus capacitance does not exceed the module's specification.

4. Do I need an external line reactor for this power supply?

We recommend a line reactor for installations with weak grids. It reduces harmonic distortion and protects input rectifiers. For standard factory networks, no reactor is required.

5. How do I verify correct installation of the Lenze E70ACPSE0304S?

Measure DC bus voltage after power-up. It should read approximately 565V DC with 400V AC input. Also, check that the green LED on the front panel stays lit. No abnormal noise should come from the unit.
