direct sunlight, or places where product is exposed to water or rain.

Never operate the product under overcurrent or short circuit condition. Insulation failure, or other damages may occur.

The application circuits and their parameters are for reference only. Be sure to verify effectiveness of these circuits and their

parameters before finalizing the circuit design. Moreover, we will not be responsible on application patent or utility model.

Excessive stress could cause damage. Therefore, please handle with care.

Use recommended external fuse to each products to ensure safe operation and compliance with the Safety Standards to which

it is approved.

The input power source to this product must have reinforced or double insulation from the mains.

Note

Consider storage of the product at normal temperature and humidity avoiding direct exposure to sunlight at environment with

minimal temperature and humidity changes. Storage of product at high temperature, high humidity and environments with severe changes in temperature and humidity might cause deterioration, and occurrence of condensation in the product.

When disposing product, follow disposal laws of each municipality.

Published EMI (CE, RE) or immunity is the result when measured in our standard measurement conditions and might not

satisfy specification when mounted and wired inside enduser equipment.

Use the product after sufficiently evaluating at actual enduser equipment.

If products are exported, please register the export license application etc. by the Government of Japan according to Foreign

Exchange and Foreign Trade Control Law.

The information in the catalog or the instruction manual is subject to change without prior notice. Please refer to the latest

version of the catalog or the instruction manual.

No part of this document may be copied or reproduced in any form without prior written consent TDKLambda.

Note : CE MARKING

CE Marking indicated on the products which is covered by this handbook is applied to CCG3024xxS with RoHS compliance and to CCG3048xxS with low voltage directive and RoHS compliance.

F1 : Input Fuse

This CCG series has no builtin fuse. Use external fuse to comply various Safety Standards and to improve safety. Moreover, use normalblow type for every power supply. Furthermore, fuse must be connected to +Vin side if Vin side is used as ground, or fuse must be connected to Vin side if +Vin side is used as ground. Consider margin over the actual input voltage to be used when selecting fuse. Moreover, consider I2t fuse rating for surge current (inrush current) during line throwin.

Input Fuse Recommended Current Rating

CCG3024xxS : 10A or lower CCG3048xxS : 6.3A or lower

C1 : External Input Capacitor

To prevent the effect of input line inductance to the power supply, connect electrolytic capacitor between +Vin and Vin terminals.

Recommended Capacitance

CCG3024xxS : 120μF or more CCG3048xxS : 47μF or more

Note) 1.Use low impedance electrolytic capacitor with excellent temperature characteristics.

(Nippon ChemiCon KZE series or equivalent)

2.When input line inductance becomes excessively high due to insertion of choke coil, operation of the power supply could become unstable. For this case, increase capacitance of electrolytic capacitor more than recommended capacitance.

Protection for Reversed Input Connection

Reverse input polarity would cause power supply damage. For cases where reverse connections are possible, connect a protective diode and fuse. Use protective diode with higher voltage rating than the input voltage, and with higher surge current rating than fuse current rating.

External Output Capacitor

This power supply is capable of operating without external output capacitor. For case of abrupt changes in load current or the line to the load is long, operation might become unstable. In this case, it is possible to stabilize the output voltage by attaching capacitor between

+Vout and Vout terminal.

Maximum capacitance of external output capacitor is shown in Table 51.

Note) For 3.3V and 5V output models, output voltage might become unstable at input voltage dips or

short interruption on connection output capacitor. In this case, it is possible to stabilize the output voltage by attaching input voltage retention diode and increase capacitance of C1 as shown in Fig.53. Use input voltage retention diode with higher current rating than fuse current rating. Moreover, choose a suitable capacitance of C1 in accordance with operating condition.
