- Page 2 F-RA-001-5R0 For Safe Use ◆ Introduction This product generates high voltage and energy. In order to use the product safely and prior to using the product, please read the instruction manual to the end before use in order to use the product safely, because there is a danger of death or serious injury due to electric shock.
- Page 3 F-RA-001-5R0 WARNING ◆ Understand the risk. Products generate high voltage and energy. An electrician or equivalent knowledge must read the instruction manual to the end and familiarize yourself with the proper use and danger of the product. If you want the product to be handled by another person, limit it to those with knowledge of electricity, and have people who are familiar with correct use and danger of the product conduct education and training before handling it, or handle the product under the supervision of those who are familiar with the proper use and danger of the product.
- Page 4 F-RA-001-5R0 WARNING ◆ Designed for indoor use Use the product indoors. Do not use it outdoors or indoors where there is a possibility of water leakage, flooding, or crown. ◆ About operating temperature and humidity Use within the range of operating temperature and humidity stated in the instruction manual. Do not use it in a place where the ambient temperature becomes higher than the operation temperature of the product or in a narrow closed place.
- Page 5 F-RA-001-5R0 CAUTION ◆ Install horizontally. Do not install the product in the reverse direction and the lateral direction. Internal heat dissipation becomes insufficient, parts deteriorate, there is a risk of smoke and fire. ◆ Do not install in the place where cool air blows directly. There is a danger of condensation, leakage current and burnout.

Page 8: Points To Be Careful In Handling
1 Introduction 1-4 Points to be careful in handling. WHEN TOUCHING LOAD AFTER TURNING OFF THE OUTPUT Make the setting of an output voltage to zero (0). Turn off the OUTPUT ON/OFF switch. 2. Check and confirm that the voltage is zero at an output voltmeter of this unit. 3. -
Page 9: Characteristics Of Bi-Polar Amplifier
1 Introduction 1-6 Characteristics of bi-polar amplifier Capacitive load Capacitive load may cause oscillation when it is more than 100pF. In such a case, insert 1Ω (10μF)～1kΩ（1000pF）power resistance in series with the output. Be careful that the frequency bandwidth is limited depending on the resistance inserted in series and the capacity under capacitive load. -
Page 10: Connection Precaution
1 Introduction Rising time （Stepping time）:The responsivity is sometimes expressed by the rising time(as shown in the drawing below). The rising time of a bi-polar amplifier at a response speed of (=frequency bandwidth) Fc(Hz) is generally acquired by “tr approximately 0.35/fc” Falling time tf is the same as tr. -

Page 16: Over Current Protection
4 Instruction for handling Over Current Protection There are two circuits installed in this power supply. A circuit is to limit normal current at 107% of rated current within 1msec. Another circuit is to limit pulse current at 1.5 times of the rated in case of swinging rectangle wave or charging capacitive in order to protect amp devices. -
Page 17: Optional Features
5 Optional Features 5 Optional Features 5-1 Cancel power outage protection (LN) Power outage protection is installed in standard, but this function can be cancelled with this option, which enables you to turn on and off power supply by AC input on and off. 5-2 Output range setting (LVs) Three output ranges (L, M, H) can be changed by output range selector switch on the front panel.
